摘要： In laser welding an optical part to a pickup case of an optical pickup device, outgas deposition on a lens surface can be inhibited, and positional shifting of the optical part can be reduced. The optical part has a lens surface facing in an optical axis direction and a protruding part formed, to be joined to the pickup case, at an end portion thereof in a direction perpendicular to the optical axis. A joint surface between the protruding part and the pickup case extends in a direction parallel to the optical axis, and the joint surface is fixed by a weld portion formed by laser irradiation. The joint surface is parallel to a bottom surface of the pickup case, and the height from the bottom surface is approximately equal to the height of the center of the lens surface.
