    Abstract: A light emitting device includes an excitation light source that emits excitation light, a wavelength conversion member, a light guide, and a light guide distal end member. The wavelength conversion member absorbs the excitation light emitted from the excitation light source, converts its wavelength, and releases light of a predetermined wavelength band. The light guide in which the center part (core) of its cross section has a refractive index that is higher than the refractive index of the peripheral portion (cladding) guides the excitation light emitted from the excitation light source to the wavelength conversion member. The light guide distal end member supports a distal end of the light guide on the wavelength conversion member side. The light guide distal end member is formed from a material that reflects the excitation light and/or the light that has undergone wavelength conversion.
