Zusammenfassung:	PROBLEM TO BE SOLVED: To accurately stop a movable part at a desired position in a stable state, and to reduce a Q value at the resonance frequency of the movable part in an optical pickup device. SOLUTION: This optical pickup device is provided with a base part 10, a movable part 30 equipped with an objective lens 31, and elastic support members 40a to 40d. Among these, the elastic support members 40a to 40d are made of wire-like members, fixed to the base part 10 at one end, and fixed to the movable part 30 at the other end, thereby supporting the movable part 30 so as to be displaceable and elastically to the base part 10. The elastic support member 40 is formed into an S shape, and a viscous member 47 is fixed to a part of the elastic support parts 40a to 40d. COPYRIGHT: (C)2005,JPO&NCIPI
