1. A light source apparatus, comprising:
an emission section in which a plurality of vertical-cavity surface-emitting laser (VCSEL) light-emitting elements is arrayed; and
a driving section configured to control the plurality of VCSEL light-emitting elements of the emission section to emit light, wherein
the driving section includes a plurality of wiring layers,
the plurality of wiring layers includes leads for electrically connecting driving elements of the driving section and the light-emitting elements,
a portion of cross-sectional area of the leads increases based on an increase in a length of the leads,
the portion of the cross-sectional area corresponds to a cross section in a plane perpendicular to an extension direction of the leads, and
at least a portion of a region including the driving elements in the driving section is disposed so as not to overlap with the emission section.
