Abstract
[Object] To implement a light source apparatus that is high in efficiency and has favorable color reproducibility. [Solution] There is provided a light source apparatus including: a light source configured to output light in a first wavelength region; and a wavelength conversion member including a first fluorescent substance and a second fluorescent substance, the first fluorescent substance being excited by the light in the first wavelength region to emit light in a second wavelength region, the second fluorescent substance being stacked on the first fluorescent substance and excited by the light in the first wavelength region and the light in the second wavelength region to emit light in a third wavelength region.
