Provided is a light emitting device with effectively improved color rendering properties. A light emitting device 1 includes: a light source 2 that emits light having the maximum intensity at a predetermined wavelength; a first phosphor (yellow phosphor) 51 that absorbs the light emitted by the light source 2 and outputs fluorescent light having the maximum intensity at a first wavelength which is longer than the predetermined wavelength; and a second phosphor (red phosphor) 52 that absorbs the light emitted by the light source 2 and outputs fluorescent light having the maximum intensity at a second wavelength which is longer than the first wavelength. An absolute value of wavelength dependency of an optical absorption rate of the second phosphor 52 at the first wavelength is set to not more than 0.6%/nm. Accordingly, the color rendering properties of the light emitted by the light emitting device 1 can be effectively improved.
