Included are, a module fixing body (1, 20; 50) having a plurality of mounting holes (20m, 20l; 50m, 50l) into which laser modules (19) are fitted and accommodated, respectively; an electricity-supplying member (32) having an end provided with electricity-supplying terminals (32b), which are connected to electricity-receiving terminals (19b) of the laser module (19) accommodated in the mounting hole (20m, 20l; 50m, 50l); and a cooling member (34, 36a; 46) that cools each of the laser modules. A groove (20g; 50g) in which the electricity-supplying member (32) is accommodated is formed in a surface of the module fixing body (1, 20; 50), and the cooling member (34, 36a; 46) is closely arranged on the surface of the module fixing body (1, 20; 50). |
