A light-emitting device of the present application includes a light-emitting element and a phosphor layer. Output light of the device is white light, which contains red, green, and blue light-emitting components emitted by red and green phosphors and a blue light-emitting element, respectively. The phosphor layer includes a phosphor such as a red phosphor, which is a nitridoaluminosilicate-based nitride phosphor, and a green phosphor. The red and green phosphors and the blue light-emitting element have emission peaks from 600 nm to less than 660 nm, from 500 to less than 560 nm, and from 440 nm to less than 500 nm, respectively. The phosphor in the phosphor layer has an excitation peak at a wavelength shorter than that of the emission peak of light emitted by the blue light-emitting element. The phosphor is activated with Eu 2+ or Ce 3+ . |
