Abstract:
1. A light source device, comprising: a substrate on which a first through-hole and a second through-hole are formed; a semiconductor light-emitting element mounted on the substrate; a flow passage for a fluid in which the semiconductor light-emitting element is arranged, the flow passage being formed so as to pass through a light exit surface of the semiconductor light-emitting element via a mounting surface of said substrate on which the semiconductor light-emitting element is mounted; a first member configured to form said flow passage with the substrate; a second member located on a side opposite a side of the substrate on which the semiconductor light-emitting element is mounted, and including a first pipe line that is connected to the first through-hole and a second pipe line that is connected to the second through-hole; and a heat radiation portion located on said second member, wherein the first through-hole and the second through-hole communicate with the flow passage, wherein the fluid flows from at least one of the first through-hole and the second through-hole into the flow passage, and wherein the first pipe line and the second pipe line each includes a projection portion projected from a side of the second member to a side of the first member, the projection portion of the first pipe line being inserted into the first through-hole, and the projection portion of the second pipe line being inserted into the second through-hole.
