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 memberincludes a matrixand phosphor particlesdispersed in the matrix, wherein the matrixis formed of a porous oxide bodyhaving an average pore diameter of 50 μm or less.
