PROBLEM TO BE SOLVED: To provide a light-emitting device having a predetermined color tone.
SOLUTION: This light-emitting device has a pumping source 10 for emitting a pumped light 1, a light guide 20 for transmitting the pumped light 1 emitted from the pumping source 10, and a wavelength conversion member 30 for carrying out wavelength conversion, after absorbing the light from the pumping source 10. The wavelength conversion member 30 has a first wavelength conversion member and a second wavelength conversion member, the emission peak wavelength of the first wavelength conversion member is substantially the same as the emission peak wavelength of the second wavelength conversion member, the relative emission efficiency is 70% or higher in the excitation spectrum of the first wavelength conversion member at the emission peak wavelength of the pumping light and the relative emission efficiency is 60% or lower in the excitation spectrum of the second wavelength conversion member, at the emission peak wavelength of the pumping light.
