PROBLEM TO BE SOLVED: To cool a laser light-emitting element with a simple structure.SOLUTION: A light source device 20 includes a plurality of laser light-emitting elements 2a-2c in which an end of a pin P1 supporting a light emitter 25 protrudes to the outside and which are attached to a housing 11. The laser light-emitting elements 2a, 2c of the plurality of laser light-emitting elements, arranged at both ends, are attached to the housing 11 so that the pin P1 is positioned on an end side from the centre of the laser light-emitting elements. Thus, heat generated by the light emitter is conducted to the pin P1 protruding to the outside and radiated to the outside. At this time, heat radiation from the pin P1 can be efficiently performed because the pins P1 are separated from each other among the plurality of laser light-emitting elements. |
