1. Management Policy

Advantest's Basic Management Policy
- -----------------------------------

         Advantest believes that its mission is to support leading-edge
technology at its forefront. Its basic management policy consists of the
following elements: increasing corporate value, improving shareholder and
customer satisfaction and achieving excellence.


Business Strategy
- -----------------

         Advantest is focused on improving operating results through
establishing an operating structure that responds timely to market changes,
promoting early development of key future technologies and providing timely
customer solutions under the concept of "GETsolution."(1) To achieve these
objectives, Advantest is driven to further strengthen its product development
operations and improve production efficiency by selectively focusing on certain
businesses, while strengthening its overseas operations in the U.S., Europe and
Asia.

         Further, Advantest seeks to achieve better transparency and strengthen
its corporate branding by stressing the importance of corporate social
responsibilities, enhancing its disclosure process and compliance system, and
addressing environmental as well as human rights issues.

         Since October 2001, Advantest has launched a company-wide initiative
called "Initiative 21." This initiative seeks to promote new ideas and
improvement strategies at all levels of the company, from divisions ranging from
sales, development and manufacturing to maintenance and administration, with an
aim toward strengthening the company's competitiveness. Advantest expects to
achieve further growth and fulfill its social mission by having each employee
take the initiative to tackle new issues. This initiative will continue
throughout FY2004, the year of Advantest's 50th anniversary.


         *1   GETsolution (Globally Enabled Total solution) is Advantest's
              service business designed to provide a set of comprehensive
              solutions to deal with issues ranging from the design to the
              delivery of semiconductors.

Target Financial Index
- ----------------------

         In addition to such indicators of performance as profit margin, ROE and
cash flows, Advantest uses "AVA" (Advantest Value Added), a financial index
incorporating the concept of EVA(R)(2) (Economic Value Added), to measure its
business performance. Advantest will continue to set the minimum
return-on-investment ratio ("hurdle rate") for evaluating AVA at 8% and a
mid-term target at 12% with an aim to further increase corporate value and
shareholder value.


         *2   EVA(R) is a registered trademark of Stern Steward & Co.

Basic Policy on Distribution of Profits
- ---------------------------------------

         Advantest believes that shareholder value is premised on the
realization of long-term and continued growth in corporate value.

         In this regard, retained profits are invested in new businesses,
research and development, streamlining efforts and overseas expansion to enable
the strengthening of Advantest's business position and creation of corporate
value.

         With respect to the direct distribution of profits, Advantest has
adopted a policy of maintaining consistent dividend payouts subject to its
financial condition.


Advantest's Views and Policies on Lowering its Investment Unit
- --------------------------------------------------------------

         As part of its capital policy, Advantest has long recognized the
importance of increasing the market liquidity of its shares, promoting long-term
and stable holding of its shares among investors



                                      -3-

                           Advantest Corporation - Consolidated (FY2004 Interim)

and expanding its investor base. Back in August 1995, the company reduced the
minimum investment unit for its shares from 1000 to 100 shares.

         As Advantest currently considers the liquidity level of its shares to
be sufficient and expects any further reduction of investment unit to require
significant costs, it is cautious about implementing any further reductions and
will do so only after careful consideration of prevailing market conditions,
business performance, share prices and other factors.


Advantest's Basic View on Corporate Governance; State of Implementation of
Corporate Governance
- --------------------

(Advantest's Basic View on Corporate Governance)

         Advantest intends to strengthen its global competitiveness by enhancing
transparency of management to all stakeholders such as investors (shareholders)
and customers.


(State of Implementation of Corporate Governance)

(1) Description of Company Organization

         In order to ensure timely response to rapid changes in the business
environment and to strengthen corporate governance, Advantest introduced the
Executive Officer system in June 2003, and bifurcated the decision-making
function and the operations execution function.

         The Board of Directors is the ultimate decision-making organ in charge
of formulating business policies and strategies, as well as monitoring and
supervising the company's operations. The Executive Officers, on the other hand,
are delegated significant authority for executing operations speedily and
efficiently. In an effort to strengthen the company's management structure and
corporate governance, it was decided at the general shareholders' meeting held
in June 2004, that the number of directors on the Board of Directors be
increased from seven to eight.

         Advantest adopts a Board of Corporate Auditors system and the Board of
Corporate Auditors consists of four auditors, two of whom are outside corporate
auditors. Each auditor audits the Board of Directors' performance by attending
important meetings including the Board of Directors meetings and reviewing the
company's operations and assets based on auditing policies and plans formulated
by the Board of Corporate Auditors.

(2) Internal Control System and Risk Management Structure

         Advantest seeks to promote its corporate activities in accordance with
higher standards of ethics, good faith and social responsibility. Advantest's
"Code of Business Conduct" was established in order to fully delineate the
company philosophy. In June 2004, Advantest's "Code of Ethics for Directors and
Executive Officers" was effectuated to set forth the directors' and executive
officers' responsibility to act ethically and in good faith.

         In addition, Advantest established the Corporate Social Responsibility
Committee ("CSR Committee") to comprehensively monitor and supervise the
company's activities from the view of corporate social responsibility. The CSR
Committee oversees the Disclosure Committee, the Internal Control Committee, the
Committee on Environmental Conservation, the Information Security Committee, the
Human Rights Protection Committee and the Personnel Mediation Committee. The
Internal Control Committee established in January 2004, in particular, is
working to establish a structure to assess and monitor internal controls in an
effort to achieve the three objectives for internal controls: "management
effectiveness and efficiency," "reliability of financial reporting," and "legal
and regulatory compliance." Auditing Group, an internal organ of the internal
auditing function, monitors internal controls and operations on a daily basis,
identifies issues and makes recommendations as part of the business audit. In
July 2004, Advantest set forth the "Third Advantest Group Environmental Action
Program" in accordance with its environmental vision of "balancing corporate
management and environmental preservation and fulfilling sustainable growth and
social responsibilities as a company" as a mid-term plan for fiscal years 2004
through 2006.

2. Business Results and Financial Condition
(1) Business Results

Interim Fiscal Period Results
- -----------------------------

         During this interim fiscal period, business conditions affecting the
company have generally continued to be strong due to a continuing appetite for
capital expenditure in the semiconductor manufacturing industry, as stimulated
by the strong performance of digital consumer products including flat-screen
televisions and DVD recorders, and continued demands for personal computers.

         Under this environment, Advantest made concentrated efforts to increase
incoming orders and expand sales through the timely introduction of new products
that attempted to meet customer needs. In addition to its continued efforts to
reduce fixed costs, Advantest and its group companies combined forces in a drive
towards attaining profitability, including the shortening of time to market by
improving the manufacturing process, parts procurement and manufacturing
efficiencies.

         As a result of the above, as compared to the corresponding interim
period for the previous fiscal year, incoming orders increased by 56.0% to
(Y)125.2 billion and net sales increased by 135.3% to (Y)146.5 billion. Net
income before income taxes increased by 12.6 times to (Y)46.8 billion and
interim net income increased by 11.7 times to (Y)28.5 billion. Overseas sales as
a percentage of total sales was 74.3%, as compared to 60.2% in the corresponding
interim period for the previous fiscal year.

Results by Business Segment

         In conjunction with its business and organizational restructuring,
since this fiscal period, Advantest reclassified its two previous automated test
equipment and measuring instruments business segments into three business
segments: semi-conductor and component test system; mechatronics system; and
services, support and others. The comparison figures against the previous
interim period have been calculated by reclassifying the figures from the
previous interim period into the three new business segments.

         (Semi-conductor and Component Test System Segment)

         In the semi-conductor and component test system segment, flash memory
testers in the memory tester market continued to perform strongly both
domestically and overseas. In addition, DRAM testers experienced solid sales in
Japan and overseas, particularly with respect to new models such as the ultra
high-speed memory tester for next generation DDR memory and the general purpose
high-speed memory tester.

         In the SoC (System-on-a-chip)/AS (Application Specific) tester market,
strong sales of the T2000 testers based on OPENSTAR(R) continued. In addition,
SoC testers for mobile phones and digital consumer devices and testers for LCD
driver ICs continued to perform strongly particularly in Japan and Taiwan. In
addition, new products aimed at the CCD market and on-board device markets
enjoyed strong sales.

         As a result of the above, as compared to the corresponding interim
period for the previous fiscal year, incoming orders in the semi-conductor and
component test system segment increased by 70.7% to (Y)96.l billion, while net
sales of the segment increased by 176.3% to (Y)113.l billion. Operating income
in the semi-conductor and component test system segment increased by 10.5 times
to (Y)37.7 billion, as compared with the corresponding interim period for the
previous fiscal year.

         (Mechatronics System Segment)

         In the mechatronics system segment, test handlers with simultaneous
multiple handling capacity and cooling capabilities as well as device interface
products continued to perform well due to the positive growth in sales of memory
testers.

         As a result of the above, incoming orders in the mechatronics system
segment, as compared with the corresponding period for the previous fiscal year,
increased by 51.8% to (Y)24.6 billion, while net sales of the segment increased
by 111.9% to (Y)28.l billion. Operating income in the mechatronics

                           Advantest Corporation - Consolidated (FY2004 Interim)


system segment increased by 211.6% to (Y)9.9 billion, as compared with the
corresponding period for the previous fiscal year.

         (Services, Support and Others Segment)

         Incoming orders in the services, support and others segment, as
compared with the corresponding period for the previous fiscal year, increased
by 3.6% to (Y)10.0 billion, while net sales of the segment increased by 9.3% to
(Y)10.8 billion. Operating income in the services, support and others segment
increased by 33.0% to (Y)0.7 billion, as compared with the corresponding period

Distribution of Profits

         Advantest believes that it has achieved its goals for the current
interim period as presented above. Although business conditions remain
uncertain, based on the profit distribution policy described above, Advantest
expects to distribute an interim dividend of (Y)25 per share as originally
forecasted.


Prospects for the Fiscal Year
- -----------------------------

         With respect to business conditions in the upcoming future,
semiconductor-related demands are expected to continue growth resulting from the
continued success of third generation mobile phones and continued demand for
personal computers and an expected increase in demand for digital consumer
devices in the medium term. In addition, capital investment among semiconductor
manufacturers are expected to increase as 300 mm wafer-related investments are
expected and the next generation of memory devices are rolled out.

         Responding to the above situation, Advantest plans to focus on
improvement of profitability through revenue growth generated by timely
introduction of new products designed to meet customer satisfaction, continued
renovation of the manufacturing process for quick delivery and cost-cutting
efforts.

         While factors such as the temporary production and inventory
adjustments of drivers of the digital sector such as semiconductors and
electronic components and the increase in crude oil prices may have dampening
effects on Advantest's performance in the short run, Advantest's current
estimates for the full year are as follows:

         (Consolidated)
                                                                   (million yen)

Profit Distribution Forecast

         Based on the business prospects and profit distribution policy
described above, Advantest expects to pay yearend dividends of (Y)25 per share
(or (Y)50 per share for the fiscal year including an interim dividend of (Y)25
per share) as originally forecasted.

(2) Financial Condition


         Cash and cash equivalents held at September 30, 2004 were (Y)139.9
billion, an increase of (Y)38.7 billion from March 31, 2004. Significant cash
flows during this interim fiscal period and their causes are described below.

         Net cash provided by operating activities was an inflow of (Y)44.5
billion. This amount was primarily attributable to net income of (Y)28.5 billion
and a (Y)l7.1 billion decrease in inventories.

         Net cash used in investment activities was an outflow of (Y)5.3
billion. This amount was primarily attributable to capital expenditures of
(Y)5.0 billion, including capital expenditures related to equipment for leasing.

         Net cash used in financing activities was an outflow of (Y)2.2 billion.
This amount was primarily attributable to the payment of dividends ((Y)2.4
billion).

(Notes)  1. Advantest regrouped its two business segments - "Automated Test
         Equipment" and "Measuring Instruments"- into three business
         segments- "Semiconductor and Component Test System", "Mechatronics
         System" and "Services, Support and Others". Certain reclassifications
         have been made to the business segment information for FY2003 interim
         and FY2003 to conform presentation used for FY2004 interim.
         2. Adjustments to operating income (loss) in Corporate principally
         represent corporate general and administrative expenses and research
         and development expenses related to fundamental research activities
         that are not allocated to operating segments.
