An objective lens driver comprises an objective lens, a lens holder, a plurality of support members for supporting the lens holder in such a manner as to enable the objective lens to move along the focusing direction and along the tracking direction, a drive means for driving the lens holder, a fixing member provided with a viscoelastic member formed to hold each support member, each support member including a linear section linearly formed to connect to viscoelastic member provided in the fixing member and to the lens holder, and at least one arm branching from somewhere between the ends of each linear section so as to reduce resonance of each support member generated when the lens holder is driven by the drive means.
