Abstract
A wavelength conversion member includes: a sintered body that has a light incidence face, a light emission face, and a light reflecting face that is different from the light incidence face and the light emission face, wherein the sintered body contains phosphor particles. The light reflecting face of the sintered body has a plurality of recessed portions. A distribution of the phosphor particles at the light reflecting face is lower than a distribution of the phosphor particles at a cross-section inside the sintered body.
