PROBLEM TO BE SOLVED: To provide a laser device manufactured by a specific structure so as to compose laser beams from a plurality of laser arrays to obtain a high output. SOLUTION: A first laser unit 3 for outputting first output laser beams, and a second laser unit 4 which has a mounting part of a different thickness from the first laser unit 3 for outputting second output laser beams in a direction perpendicular to the first output laser beams, are mounted on a metallic base 9 via insulating sheets 13, 21, respectively, a mirror 42 for reflecting a progressive direction of the second output laser beams to the identical direction to the first output laser beams is mounted thereon, and the first and second laser units 3, 4 are electrically series-connected by a wiring to constitute the laser device 1. Thus, even when the laser beams from the plurality of laser arrays are composed to obtain a sufficiently high output, a cooling can be suitably performed, and when an operator touches the device, he/she can be prevented from receiving an electric shock.
