| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an optical pickup for alleviating resonance of an objective lens, which is generated when a tilt of the objective lens is controlled. SOLUTION: The optical pickup includes the objective lens, a lens holder for holding the objective lens, and an actuator for rotating the lens holder to control the tilt of the objective lens. The objective lens is bonded to the lens holder via adhesive applied on a plurality of adhesive points. The adhesive points between the objective lens and the lens holder are asymmetrical to a plane including the rotation axis of the lens holder and the optical axis of the objective lens.
