PROBLEM TO BE SOLVED: To provide an inexpensive optical scanner by which the interval adjustment of a plurality of light beams can be made easily whole maintaining the interval and to provide a light source device used for the optical scanner. SOLUTION: Because a through hole 60A is formed for a platy member 60 at a position opposed to the upper end surface 46C of a laser holding member 46, a screw 64 can be inserted. Besides, the screwing of the screw 66 is possible at the free end side of the platy member 60, and the tip part of the screw 66 is abutted on an elastic piece 68. The elastic piece 68 is placed between the platy member 60 and the upper end surface 46C in almost parallel to the platy member 60 and the upper end surface 46C. The screwing of the screw 64 is possible to the elastic piece 68. Here, the elastic piece 68 bends, the curved piece 54 bends downward and then an upper end surface 46C on which the screw 64 abuts moves a little in the bending direction of the elastic piece 68. Thus, the fine adjustment is possible by using the cantilever elastic piece 68.
