摘要： In an optical pickup device, a side surface parallel in the optical axis direction of an optical component is respectively fixed with an adhesive at wall surfaces (internal walls) provided opposing with each other of an accommodation case. In a part of the wall surfaces of the accommodation case, a recessed channel to be filled with the adhesive is formed. The recessed channel is provided with a stepped portion along the optical axis of the optical component at the wall surfaces of the accommodation case. A gap between the relevant side surfaces and the side surface of the optical component is formed to be reduced symmetrically toward both end portions from the center in the optical axis direction of the optical component. Accordingly, bonding strength is never lowered and position of the optical pickup device is stably maintained in an optical system.
