Disclosed is a semiconductor light-emitting device (10) comprising a semiconductor chip (12) which emits light having a wavelength from blue to ultraviolet region, and a sealing unit (16) formed in at least a part of the path where the light passes through. The sealing unit (16) contains a sealing material (16d) composed of a composite material, and a fluorescent material (16c). The composite material contains a base material (16a) composed of a resin and fine particles (16b) which are dispersed in the base material (16a) and composed of an inorganic material having an effective particle diameter of not more than one fourth of the wavelength of the light inside the base material (16a). |
