Claim Text:
1. A light-emitting module, comprising: a substrate; at least one semiconductor light-emitting element arranged on a main surface of the substrate; and a heat transfer member thermally connecting at least a portion of an outer circumferential surface of the semiconductor light-emitting element with the main surface of the substrate, and transferring heat produced by the semiconductor light-emitting element to the substrate, wherein the heat transfer member includes a base material that is optically transmissive, and particles of an optically transmissive material that are dispersed within the base material and have higher thermal conductivity than the base material, wherein the particles include first particles of a first type of optically transmissive material, and second particles of a second type of optically transmissive material, an average diameter of the first particles is greater than a wavelength of red light, an average diameter of the second particles is smaller than a wavelength of blue light, and the first type of optically transmissive material has higher thermal conductivity than the second type of optically transmissive material.
