A light emitting device (1) includes: three or more light emitting units (10, 20, 30) that individually include blue light emitting element, a wavelength range of the blue light emitting element accommodated in respective packages being different from each other. The light emitting device mixes output lights from the light emitting units (10, 20, 30) to output white light of a predetermined chromaticity. In an xy chromaticity diagram, the chromaticity of the output light from each of light emitting units (10, 20, 30) is located at a distance from the predetermined chromaticity. The difference between the chromaticity of the output light from each of the light emitting units (10, 20, 30) and the predetermined chromaticity is not greater than 0.04.
