PROBLEM TO BE SOLVED: To provide a laser scanner in which heat generated in a laser element is sufficiently radiated and a fitting structure is furnished with which the position of projected light projected from the laser element is easily adjusted with respect to an optical axis. SOLUTION: Grooves 11a for holding the circumferential part of the flange 12a of the laser element 12 are formed on holding members 11, and the laser element 12 is held by the holding members 11 by inserting the circumferential part of the flange 12a into the grooves 11a. The periphery of the laser element 12 including the flange except a part which is inserted into the grooves 11a of the holding members 11 is open, thus a high heat radiation effect is available. The flange 12a inserted into the grooves 11a of the holding members 11 is freely movable in Y-Z plane perpendicular to the optical axis (X axis) of laser light, and the optical axis position of the laser light is accurately adjustable.
