The present invention provides a light emitting device that emits light having a color rendering property close to that of sunlight in the evening compared to conventional light emitting devices. A light-emitting device according to one embodiment of the present invention includes a first phosphor that emits fluorescence having a peak wavelength of 445 nm to 490 nm, and a first phosphor that emits fluorescence having a peak wavelength of 491 nm to 600 nm. 2 and a third phosphor that emits fluorescence having a peak wavelength of 601 nm or more and 670 nm or less, and light having a peak wavelength shorter than the peak wavelength of fluorescence emitted by the first phosphor. A light emitting element that emits light, and the ratio x of the mass of the first phosphor to the total mass of the first phosphor, the second phosphor, and the third phosphor, The mass ratio y of the second phosphor and the mass ratio z of the third phosphor are 0.586 ≦ x ≦ 0.734, 0.017 ≦ y ≦ 0.081, 0.239 ≦ z ≦ 0. .384, x + y + z = 1 Plus.
