Abstract

A light source device of the present invention includes a light source that emits first light, a wavelength conversion member that converts the wavelength of the first light made incident on a surface of the wavelength conversion member on the side of the light source and emits second light different from the first light, and a supporting member that supports the wavelength conversion member at an end portion of a surface of the wavelength conversion member on the side of the light source. A light absorbing member is provided between a surface of the wavelength conversion member on the side of the light source and the supporting member.
