(Qualitative Information Regarding Consolidated Financial Results)

   During the first quarter of the current fiscal year, as a result of progress
in the inventory adjustment for digital consumer products such as flat screen
televisions, DVD recorders and cellular phones, and due to strong sales in
personal computers, particularly notebook computers, Advantest's operating
environment was steady due to the trend towards recovery in capital expenditures
by the semiconductor manufacturers. In such an environment, Advantest introduced
new products for next-generation semiconductors in order to meet customers'
needs, as an effort to increase incoming orders and sales. Advantest continued
to make efforts to improve productivity and reduce costs. As a result, during
the first quarter of the current fiscal year, incoming orders decreased by 21.7%
to JPY 60.8 billion from the same quarter of the previous fiscal year and net
sales decreased by 27.8% to JPY 52 billion from the same quarter of the previous
fiscal year. Income before income taxes decreased by 46.5% to JPY 12.1 billion
from the same quarter of the previous fiscal year and net income for the current
fiscal year decreased by 44.1% to JPY 7.8 billion from the same quarter of the
previous fiscal year. Overseas sales as a percentage of total sales was 69.5%
compared with 73.6% in the same quarter of the previous fiscal year.

(Results by Business Segment)

   During the first quarter of the current fiscal year, in the Semiconductor and
Component Test System segment, incoming orders, net sales and operating income
were JPY 46.9 billion, JPY 39.2 billion and JPY 11.2 billion, respectively, as
semiconductor test systems for flash memory, MPUs and LCD driver IC maintained
steady sales, despite restrained capital expenditures by some of the
semiconductor manufacturers for DRAM semiconductor test systems due to low DRAM
prices. In the Mechatronics System segment, incoming orders, net sales and
operating income were JPY 10.8 billion, JPY 9.3 billion and JPY 2.2 billion
respectively, as a result of steady demand in device interface products for
DDR-SDRAM and flash memory, despite lagging sales in test handlers for DRAM. In
the Services, Support and Others segment, incoming orders, net sales and
operating income were JPY 4.5 billion, JPY 4.1 billion and JPY 0.8 billion
respectively.

(Qualitative Information Regarding Changes in Consolidated Financial Position)

   With respect to Advantest's financial position for the first fiscal quarter,
total assets increased by JPY 9.9 billion to JPY 306.7 billion, due to the
increase of accounts receivables by JPY 7.4 billion and inventory assets by JPY
6.1 billion. Total liabilities increased by JPY 3.2 billion to JPY 93.2 billion,
primarily due to the increase of accounts payable by JPY 6.5 billion.
Shareholders' equity was JPY 213.4 billion and equity-to-assets ratio decreased
by 0.1 percentage points to 69.6% from the last fiscal year end.

(Cash Flow Statements)

   Cash and cash equivalents at the end of the first fiscal quarter decreased by
JPY 3.3 billion from the end of the previous fiscal year to JPY 117.6 billion.
   Cash flows from operating activities was an outflow of JPY 0.7 billion, which
consisted of an increase in account receivables and inventory assets despite
posting net income for current period of JPY 7.8 billion.
   Cash flows from investing activities was an outflow of JPY 1.3 billion, which
consisted primarily of capital expenditures on tangible fixed assets including
lease assets.
   Cash flows from financing activities was an outflow of JPY 2.1 billion, which
consisted primarily of dividends paid.

- -----------------------------------------------------------------------------------------------------------


(Qualitative Information Regarding Projected Results)

   With respect to Advantest's projected results in the second quarter and
beyond, the prospect for semiconductor related capital expenditures remain
positive with the recovering demand attributed to the progress in inventory
adjustment of digital consumer products and the increase in demand for DRAM
towards the year end sale season, despite the uncertainties regarding the
economy attributable to inflating oil prices and fluctuations in the currency
exchange rates against the Chinese yuan and the US dollar. Earnings forecast for
the interim and the fiscal year ending March 2006, therefore, remains unchanged.

(Note) Figures presented in the Quarterly Financial Results have been rounded to
the nearest million yen.
