A JEM phase phosphor having excellent luminous efficiency is obtained, and the first phosphor and the second phosphor are used as the first phosphor, and the fluorescence from the first phosphor is emitted. Provided is a light emitting device which is hardly absorbed by a second phosphor. The first phosphor is a JEM phase phosphor having a light absorption rate of 30% or less at a wavelength complementary to the emission wavelength. Further, in the first phosphor of the light emitting device in which the first phosphor and the second phosphor emitting fluorescence having a wavelength longer than that of the first phosphor are combined, the second phosphor The light absorption rate at the emission wavelength is 30% or less.
