Abstract
A light source apparatus includes a first laser light emitter that emits first light, a wavelength converter that converts the first light into second light, a base including a first support part that supports the first laser light emitter and a second support part that supports the wavelength converter, and a first optical element that guides the first light to the wavelength converter. The first optical element has a first light incident surface which faces the first laser light emitter, a first reflection surface that reflects the first light emitted from the first light incident surface and deflects the optical path of the first light, and a first light exiting surface which faces the wavelength converter and via which the first light reflected off the first reflection surface exits. The first light incident surface, the first reflection surface, and the first light exiting surface intersect with each other.
