1. A light source device comprising:
a light source adapted to emit a first light; a wavelength conversion element adapted to emit a second light in a first wavelength range due to irradiation of the first light; and a wavelength separation element to which the second light is input, the wavelength separation element being composed of a single member, wherein the wavelength separation element generates a third light reduced in light intensity of a component in a second wavelength range among a component in the first wavelength range compared to the second light, wherein the second wavelength range includes a fifth wavelength range, which is a wavelength range between a third wavelength range on a long wavelength side and a fourth wavelength range on a short wavelength side among the first wavelength range, and wherein the third light includes a component in the third wavelength range and a component in the fourth wavelength range, but the component in the filth wavelength range is reduced.
