Nidec Revises Upward Year-End Dividend Forecast

KYOTO, Japan--April 25, 2005--Nidec Corporation (the "Company") resolved at a meeting of its Board of Directors today to revise upward the year-end dividend forecast for the year ended March 31, 2005 to 25 Yen per share.

Reasons for revision

Nidec Corporation's dividend policy provides for the stable payment of dividends in a manner reasonably reflecting the Company's earnings growth and in principle applies approximately 10% of the Company's consolidated fiscal net income to dividend payments.

The Company announced in its interim financial report released on October 29, 2004 that it would raise its forecast for interim and year-end per share dividends for the year ended March 31, 2005 by 5 Yen to 20 Yen , reflecting the Company's favorable fiscal performance, which surpassed original expectations. The payment of the interim dividend of 20 Yen per share was implemented on schedule.

The Company decided to further increase the year-end per share dividend by 5 Yen to 25 Yen as a result of its consolidated results for the year ended March 31, 2005. The Company's full-year dividend for the year ended March 31, 2005 will increase accordingly by 15 Yen , to 45 Yen per share.
