摘要： In a laser welding method, detachment is suppressed and dislocation of an optical component is reduced by improving adhesiveness of an interface of a welded part to thereby improve yield and reliability of an optical pickup device. A manufacturing method of an optical pickup device includes: a step of bringing the optical component into contact with the holding member; a step of irradiating laser light; and a step of melting the holding member through the irradiation to weld the holding member to the optical component, wherein before the laser light is irradiated, surface roughness of a portion of the optical component to be welded is greater than surface roughness of the holding member in contact with the portion, whereby the melted holding member enters into an uneven part on a front surface of the optical component, improving adhesion strength.

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.
