Abstract
Disclosed is a wavelength conversion member that is provided with: a light transmissive member including a light input plane into which excitation light is inputted, and a light output plane from which wavelength converted light is outputted; and a semiconductor fine particle phosphor, which is dispersed in the light transmissive member, and which absorbs the excitation light, converts the wavelength, and emits light. The dispersion concentration of the semiconductor fine particle phosphor in the direction parallel to the light traveling direction, i.e., the direction connecting the light input plane and the light output plane, is lower than the dispersion concentration of the semiconductor fine particle phosphor in the direction orthogonal to the light traveling direction.
