Nobuyuki Idei

Nobuyuki Idei (出井 伸之, Idei Nobuyuki; born November 22, 1937) is a Japanese businessman. He was a former Chairman and Group Chief Executive Officer of Sony Corporation until the 7th March 2005. He is also a director of General Motors, Baidu, Yoshimoto Kogyo and Nestlé.

After a stroke sidelined former chairman Akio Morita, Sony CEO and new chairman Norio Ohga selected Idei to be the next president, a choice that raised eyebrows at Sony. His sweeping reorganizations of the company included trimming the board of directors from 38 members dominated by company management to 10 with a substantial presence of outsiders. Already perceived as the company's driving force, Idei was formally named co-CEO in 1998 and sole CEO in 1999. In 2000, while Ohga remained Chairman of the Board, Idei became Executive Chairman and Kunitake Andō became president.

In 2003, on Ohga's retirement, Idei became the sole Chairman, and the title of Chief Executive Officer was altered to Group Chief Executive Officer. On March 7, 2005, it was announced that Idei would be succeeded on June 22 by Sir Howard Stringer.

In 2006, Idei joined the board leading Accenture. On September 28, 2011, Idei joined the Board of Directors of Lenovo.

On July 15, 2014, Idei joined the Board of Directors of ZL Technologies. ZL Technologies' CEO Kon Leong noted that "Mr. Idei joins an advisory board at ZL represented by thought-leaders from diverse backgrounds and industries. ZL Technologies' visionary approach of enabling total information governance of corporate data to reduce risks and improve strategic performance is rapidly gaining traction among the world's largest enterprises. We are excited to welcome Mr. Idei, who ranks among the top strategic advisors in the business world."

On February 5, 2015 Idei retired from Accenture's board of directors.
