摘要： It is an object of this invention to increase the rigidity of a movable part and decrease its weight. An objective lens driving apparatus has an objective lens which focuses light on the recording surface of an optical disk. The objective lens is driven by focusing coils in directions approaching and receding from the optical disk and is driven by tracking coils in the radial direction of the optical disk. The objective lens is held by a lens holder. A projecting part projecting outward from the outer side surfaces of the lens holder is formed around the entire peripheral edge of the bottom surface of the lens holder.

The optical pickup of the invention has an optical unit and an optical pickup case. The optical unit has a lens member having an optical axis, and the optical axis of the lens member is offset to one side from the center of the optical unit. The optical pickup case holds the optical unit from both sides. A thermal expansion amount of the optical unit is absorbed by compression amounts of a first adhesive and a second adhesive such that the optical axis of the lens member is not displaced when the optical unit is thermal expanded.
