摘要：
A lens holding member carrying an objective lens is movable and supported by a fixed member via a plurality of supporting members. Each supporting member includes a bent part in its base portion on the side of the fixed member. The bent part is bent in a first direction (focusing direction) and a second direction (tracking direction) that are perpendicular to each another. Each supporting member is shaped so as to make all the principal planes of the supporting member parallel to the second direction. The fixed member includes a concave, which is impregnated with a gel material so that the bent part is covered with the gel material.
