                Interim Business Report for the 65th Fiscal Year
                   (April 1, 2006 through September 30, 2006)

To Our Shareholders
- --------------------------------------------------------------------------------

       Let us report on the business results of Advantest on a consolidated
basis during the interim period of fiscal year 2006 (April 1, 2006 through
September 30, 2006).

          During this interim fiscal period, Advantest's operating environment
was overall favorable, as stimulated by continuing steady sales of consumer
digital products (such as portable audio players and flat-panel televisions)
from the previous period. Partly due to a trend of inventory adjustment of
liquid crystal panels and a reduction in capital expenditures by some
semiconductor manufacturers, we did not achieve the interim results forecasted
in our previous forecast. However, mainly due to increases in demand for
semiconductors and increases in capital expenditures by semiconductor
manufacturers for new production lines, our overall sales remained steady.

          Under this environment, Advantest made efforts to increase orders
input received and expand sales by introducing products that meet customers'
demand and providing test solutions that are targeted at its customers.
Advantest also continued to make efforts to improve productivity and cost
reduction.

          Accordingly, as compared to the previous interim fiscal period, orders
input received decreased by 5.2 % to (Y)115.2 billion, net sales increased by
12.5 % to (Y)120.5 billion, net income before income taxes increased by 38.6 %
to (Y)34.0 billion, and net income for the interim fiscal period increased by
51.9 % to (Y)22.2 billion. Overseas sales as a percentage of total sales were
60.0%, as compared with 67.7 % in the previous interim fiscal period.

          Interim dividends of (Y)35 per share as compared to (Y)25 in the
corresponding interim period for the previous fiscal year will be distributed to
shareholders recorded in the register as of September 30, 2006 beginning on
December 1, 2006, as resolved by the Board of Directors' Meeting on October 27,
2006.

          We look forward to your continued support and guidance.

                                                                   November 2006

  after such stock split.
** "Net income (loss) per share (basic)" was calculated based on the average
  number of issued shares (excluding treasury stock) during the period.
***"Stockholders' equity per share" was calculated based on the number of issued

Business Results by Segment

Semiconductor and Component Test System Segment
          In this segment, overall sales was positive despite a trend of
inventory adjustment of the liquid crystal panels used for personal computers
and a reduction in capital expenditures by some semiconductor manufacturers.
Such positive sales was primarily due to increased demand for new test systems
resulting from a growth in sales of consumer digital products, among other
things.
          In the memory semiconductor test system market, because the price of
DRAM semiconductors remained stable and manufacturers of DRAM semiconductors
promoted capital expenditures for mass production of DDR2-DRAM semiconductors,
demand for front-end test systems for DRAM semiconductors was overall positive
in Japan, Taiwan and Korea, among other countries. However, the results of
back-end test systems for DRAM semiconductors did not achieve our previous
forecasts. In addition, sales of test systems for flash memory semiconductors
remained steady, due to stable demand for portable audio players and digital
cameras, among other things.
          In the market of non-memory semiconductor test system, sales of SoC
semiconductor test systems for devices used in consumer digital products and
car-related products was primarily favorable in Japan. However, sales of test
systems for non-memory semiconductors used in LCD driver IC was weak in the
latter half of this interim fiscal period as a result of inventory adjustment of
liquid crystal panels in Japan and in Taiwan. Furthermore, demand for the T2000,
a test system compatible with OPENSTAR(R)*, which was very favorable in the
previous fiscal year, was low due to slow down in the demand.
          As a result of the above, orders input received was (Y)82.0 billion
(12.5 % decrease in comparison to the previous interim fiscal period), sales was
(Y)86.0 billion (6.4 % increase) and operating income was (Y)26.5 billion (26.3
% increase).

 *OPENSTAR(R): The name of an open architecture standard published by the STC
               (Semiconductor Testing Consortium, Inc.). OPENSTAR(R) is a
               registered trademark or a trademark of STC in the United States,
               Japan and other countries.


Mechatronics System Segment

          Sales of memory semiconductor test handlers was favorable, primarily
due to positive sales of test handlers for flash memory semiconductors. Sales of
non-memory semiconductor test handlers remained steady in connection with test
handlers for SoC semiconductors used for consumer digital product devices. Sales
of device interface products was also steady, due to an increase in demand for
flash memory semiconductors and semiconductors for SoC.
          As a result, orders input received was (Y)25.5 billion (17.6 %
increase in comparison with the previous interim fiscal period), sales was
(Y)26.7 billion (30.1 % increase) and operating income was (Y)7.6 billion (64.5
% increase).

Services, Support and Others Segment

         In this segment, orders input received was (Y) 9.4 billion (4.0 %
increase in comparison with the previous interim fiscal period), sales was (Y)
9.7 billion (13.2 % increase) and operating income was (Y) 1.4 billion (27.6 %
decrease).


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

          With respect to its operating environment in the fiscal year,
Advantest expects a rapid increase in demand for DDR2-DRAM used in personal
computers resulting from, among other things, the planned launch of a new
operating system for personal computers in January 2007. Advantest also expects
to see expanded volume and application of flash memory semiconductors used for
mobile telephones, portable audio players and digital cameras. Furthermore, a
continuous increase in demand is anticipated for semiconductors used for
car-related products and digital consumer products (due to wider acceptance of
flat-panel televisions by consumers). With such increase in demand, Advantest
expects that demand for semiconductor manufacturing equipments will continue to
increase going forward.
          On the other hand, Advantest is concerned that restrained capital
expenditures as a result of poor supply and demand balance, an issue unique to
the semiconductor market, increased prices of raw materials such as oil, risks
relating to exchange rates, and strengthened downward pressure on prices as a
result of the above-mentioned factors may affect our results.
          In order to respond to these conditions, Advantest plans to continue
its efforts to increase orders input received and expand sales through the
timely introduction of new products that meet customers' needs by strengthening
marketing and development structure. To further strengthen its cost
competitiveness, Advantest will make continued efforts to further improve
profitability by reviewing its operational process company wide and improving
manufacturing efficiency.
          As a result of the above, net sales for the fiscal year are currently
estimated at (Y)255.0 billion, while income before income taxes is estimated at
(Y)68.0 billion and net income at (Y)43.0 billion.
