PROBLEM TO BE SOLVED: To provide an objective lens driving device for an optical pickup preventing a slack part from being abutted on a bottom surface part of a yoke even when the slack part of a flexible printed circuit board suspended across between a lens holder and the yoke is long and capable of easily confirming the state of the flexible printed circuit board even after the lens holder is loaded in the inside of the yoke. SOLUTION: In the objective lens driving device 1 of the optical pickup, the flexible printed circuit board 8 with the slack part 83 is suspended across between the lens holder 3 loading the objective lens and the cup like yoke 2 supporting the holder 3 movably in the tracking direction and focusing direction. A yoke side window opening 20 is formed on a connection part between the flexible printed circuit board 8 and the lens holder 3 and an area answering to the slack part 83 among the bottom surface part of the yoke 2. Although the yoke 2 is fixed onto a frame 9 loading an optical system leading a laser beam to the objective lens, a frame side window opening 90 is formed on the area opposite to the yoke side window opening 20 of the frame 9. |
