Abstract
A semiconductor light-emitting device 10 has a semiconductor chip 12 for emitting light having a wavelength in blue to ultraviolet regions, and a sealing portion 16 formed in at least a partial region on a passage path on which the light is passed. The sealing portion 16 includes a sealing material 16d which is a composite material including a matrix material 16a made of a resin, nano-particles 16b made of an inorganic material which are distributed in the matrix material 16a, the nano-particle 16b having an effective particle size which is ¼ or less of the wavelength of the light in the matrix material 16a, and a fluorescent material 16c.
