Abstract

The purpose is to provide a wavelength conversion member, a method for producing 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 thermally conductive particlesand phosphor particlesand the thermally conductive particlesinclude two types of thermally conductive particles different in average particle diameter from each other.
