Such a semiconductor light-emitting device (10, 30, 40) that emitted light has small directivity of light intensity and a color tone and a light output is hardly reduced is obtained. This semiconductor light-emitting device includes a semiconductor light-emitting element (1, 31) and a thin-film light diffusion portion (8, 8a, 38, 41) arranged on a light-emitting direction side of the semiconductor light-emitting element.
