Zusammenfassung:A light-emitting device in an aspect of the present invention includes at least one light emitter, a first phosphor, and a second phosphor. The first phosphor emits, in response to light emitted from the at least one light emitter, light having a first peak wavelength in a wavelength region of 400 to 500 nm in an emission spectrum of light to be emitted externally. The second phosphor emits, in response to light emitted from the at least one light emitter, light having a second peak wavelength in a wavelength region of 500 to 600 nm in the emission spectrum. The at least one light emitter has a third peak wavelength in a wavelength region of 315 to 400 nm in the emission spectrum.
