Light-emitting device and illumination apparatus

A light-emitting device comprises a semiconductor light-emitting element that emits blue-violet or blue light and a fluorescent material that absorbs all or a part of the light emitted by the semiconductor light-emitting element and emits fluorescence of wavelengths different from that of the light, wherein the fluorescent material comprises a mixture of a first fluorescent material that emits green or yellow-green light, a second fluorescent material that has a longer emission wavelength than that of the first fluorescent material and emits yellow-green, yellow, or yellow-red light, and a third fluorescent material that has a longer emission wavelength than the second fluorescent material and emits yellow-red or red light, and the first fluorescent material is a europium-activated P-SiAlON fluorescent material, the second fluorescent material is a europium-activated +--SiAlON fluorescent material, and the third fluorescent material is a nitride crystalline red fluorescent material of the general formula of (Ca,Eu)AlSiN 3 .
