Abstract
A method of manufacturing a wavelength conversion member that includes a sintered body having a light incidence face, a light emission face, and a light reflecting face different from the light incidence face and the light emission face, the method comprising: providing a sintered body containing inorganic particles and phosphor particles, and forming a plurality of recessed portions on the light reflecting face of the sintered body, which comprises acid treating the sintered body.

A method of manufacturing a wavelength conversion member that comprises a sintered body having a light incidence face, a light emission face, and a light reflecting face different from the light incidence face and the light emission face, the method comprising:
- providing a sintered body containing inorganic particles and phosphor particles;
- and
- forming a plurality of recessed portions on the light reflecting face of the sintered body, which comprises acid treating the sintered body.
A wavelength conversion member comprising:
- 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,
- wherein the light reflecting face of the sintered body has a plurality of recessed portions, and
- wherein 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.
