A light emitting device includes a light emitting element that emits a light having a peak emission wavelength in a wavelength range of not less than 410 nm and not more than 425 nm, and a phosphor emitting a fluorescence having a peak at a longer wavelength side than the peak emission wavelength of light emitted from the light emitting element. A general color rendering index Ra of fluorescence emitted from the phosphor is not less than 95. A general color rendering index Ra of mixed light of light emitted from the light emitting element and fluorescence emitted from the phosphor is higher than a general color rendering index Ra of fluorescence emitted from the phosphor. A color rendering index Rf of the mixed light is not less than 96.
