Abstract
A light source apparatus according to an aspect of the present disclosure includes a light source section that emits first light and excitation light having a first wavelength band, a light guide that causes the first light emitted from the light source section to propagate, a wavelength converter including a phosphor that emits second light having a wavelength band different from the wavelength band of the excitation light when the wavelength converter is excited with the excitation light emitted from the light source section, and a light combiner that combines the first light having exited out of the light guide with the second light having exited out of the wavelength converter. The light guide and the wavelength converter are disposed side by side, and a light transmissive member that transmits the first light is provided between the light source section and the light guide.
