PROBLEM TO BE SOLVED: To provide an optical head high in holder holding force and capable of being made small in size and thin in thickness. SOLUTION: This integrated optical head 120 is fixed to a base 110 by a screw 130. In the front face of the base 110, a through-hole 114 is provided for inserting a cylindrical holder 150 having a collimator lens 140 attached, and adjacently to this through-hole 114, a recessed part 116 is formed for housing a U-shaped leaf spring 160. First, the leaf spring 160 is arranged in the recessed part 116, and then the holder 150 is inserted into the through-hole 114 and assembled. The leaf spring 160 pushed into the recessed part 116 is held in the recessed part 116 by its own restoring force. Also, the holder 150 inserted into the through-hole 114 pushes away the leaf spring 160, and thus the holder 150 is held in the through-hole 114 by the restoring force of the leaf spring 160. |
