Abstract
The purpose is to provide a wavelength conversion member, a method for manufacturing the wavelength conversion member, and a light-emitting device, which are capable of reducing the temperature rise of the wavelength conversion member and thus reducing the decrease in luminescence intensity with time and deformation and discoloration of constituent materials. A wavelength conversion member 10 includes a matrix 1 and phosphor particles 3 dispersed in the matrix 1, wherein the matrix 1 is formed of a porous oxide body 2 having an average pore diameter of 50 μm or less.
