PROBLEM TO BE SOLVED: To secure a stable drive characteristic by supporting a lens holder holding an object lens to a fixed member and respectively supplying independent currents to all respective focusing, tracking and tilt correcting driving coils of the lens holder side only with an elastic support member power supplying to the lens holder side related to an object lens driving device used for an optical disk device. SOLUTION: This device is constituted of the lens holder 22 holding the object lens 23 on a support base 21, a focusing driving means moving the lens holder 22 in the optical axial direction of the objective lens 23, a tracking driving means driving it in the direction intersecting with the optical axis of the object lens 23 and a tilt correction driving means correcting a tilt in the direction intersecting with the optical axis of the object lens 23 and the elastic support member 33 supporting the lens holder 22 to the fixed member and having at least two-layered conductive layer supplying power to respective driving means. |
