Abstract

A light source apparatus of the present invention has a plurality of semiconductor laser devices and a holding member; the semiconductor laser device includes: a semiconductor laser element; a placing body on which the semiconductor laser element is mounted; a substrate on which the placing body is biased to one side thereof; and a pair of terminals electrically connected to the semiconductor laser element, biased to the other side of the substrate and protruding from the substrate, and the holding member includes: holes aligned in at least a pair of rows; a thin-walled section on which the holes are arranged, the thin-walled section being formed by providing at least a pair of depressions on the other side; and a thick-walled section provided adjacent to the thin-walled section. The semiconductor laser device is mounted on one side of the holding member and the placing body of the semiconductor laser device is disposed on the thick-walled section, and the pair of terminals are exposed through the holes from the other side of the holding member.
