摘要： PROBLEM TO BE SOLVED: To solve the problem that a substrate and an optical device cannot be welded or may slip off by vibration or impact due to a junction part having the area reduced even in the case of successful welding, because the volume of metal of a holding tool melted during laser welding is reduced in the case that ridges of the bottom of the holding tool are chamfered during laser welding and fixing between the substrate and the optical device. SOLUTION: The optical device and the substrate are fixed by laser welding and fixing, and the size of chamfered parts of ridges in welding parts of the optical device holding tool is set to ≤0.3 mm.
