1. A light source device comprising:
a first substrate having a first mounting surface;
a second substrate having a second mounting surface that opposes the first mounting surface;
a first laser diode directly or indirectly supported by the first mounting surface;
a second laser diode directly or indirectly supported by the first mounting surface;
a third laser diode directly or indirectly supported by the second mounting surface; and
a frame that defines a space for housing the first laser diode, the second laser diode, and the third laser diode, the frame being in contact with the first and second mounting surfaces, wherein
the emission point of the third laser diode is positioned between the emission point of the first laser diode and the emission point of the second laser diode in the width direction, and
in a plan view, when viewed in the direction perpendicular to the first mounting surface, at least one of the first laser diode or the second laser diode at least partially overlaps the third laser diode.
