PROBLEM TO BE SOLVED: To propose an optical head device, in which the accurate positioning for optical components is allowed by using a frame body consisting of a photosensitive glass mounted on a base. SOLUTION: In the optical head device 1, the frame body 7 consisting of the U-shaped photosensitive glass is mounted on the base 3 having the constitution laminated with a metallic wiring substrate 31 and a metallic base frame 32, and a light receiving/emitting element 4, 1st and 2nd optical elements 61, 62 and a collimator lens 63 are positioned with this frame body 7. For the optical elements 61, 62, 63 held by the frame body 7, the fine adjustment for the mounting position is allowed from the rear side of an opening part through this opening part opened on the base 3. Consequently, the accurate positioning is attained for each optical element by the simple work. |
