An optical pickup which is configured to suppress resonances in the objective lens which are caused during tilt control of the objective lens is provided. The optical pickup device includes an objective lens, a lens holder for retaining the objective lens, and an actuator for rotating the lens holder to control tilt of the objective lens. The objective lens is bonded to the lens holder via adhesives applied at a plurality of adhesion positions. The adhesion positions at which the objective lens and the lens holder are bonded are asymmetrical relative to a plane which includes the rotation axis of the lens holder and the optical axis of each objective lens.
