摘要： PROBLEM TO BE SOLVED: To stably hold position accuracy without reducing adhesive strength even when only both sides of optical parts are bonded to a housing case in an optical pickup device. SOLUTION: A side plane 1s being parallel to an optical axis direction of the optical parts is bonded and fixed to a housing case 2 by adhesive 3. At the case, concave grooves 4, 5 for filling are formed at side planes 1s, 2s to which the housing case 2 or the optical parts 1 is bonded. In a gap for adhesion, gaps (a) in both ends of the optical axis direction are made smaller than a gap in the center part. Level difference parts of the concave grooves 4, 5 for filling adhesive are made slopes, the gap for adhesion is made smaller substantially symmetrically from the center part of the optical axis direction to the both end parts.
