PROBLEM TO BE SOLVED: To provide a laser beam irradiating device, having small size, high resolution, and high flexibility of laser beam scanning design, and using a semiconductor laser which is usable for distance measurements, or the like. SOLUTION: This laser beam irradiating device 100 has a semiconductor laser array 11, having a plurality of light-emitting points L1-L5 arranged side by side in one direction; a lens 25, arranged in the crossing state with a beam emission surface (XY-surface) constituted in the array direction (X-direction) of the plurality of light-emitting points L1-L5 and in the emission direction (Y-direction) of the laser beam, on the front in the emission direction of the laser beam emitted from each light-emitting point L1-L5 of the semiconductor laser array 11; and a prism array 40, wherein prisms P1-P5 corresponding to each light-emitting point L1-L5 are arranged side by side in one direction, in the crossing state with the beam emission surface (XY-surface) between the semiconductor laser array 11 and the lens 25.
