The present invention provides a light-emitting device having an excitation source which emits a light having a wavelength of from 420 to 500 nm and a phosphor in combination, and having a high luminance. A light-emitting device having a first illuminant which emits a light having a wavelength of 420 to 500 nm and a second illuminant which emits a visible light when irradiated with the light from the first illuminant, characterized in that the second illuminant contains a phosphor, and the object color of the phosphor satisfies L*‰§90, -22‰¦a*‰¦-10, and b*‰§55, in the L*, a*, b* color system. |
