Abstract
A light-emitting device includes a light-emitting element, a phosphor layer, a reflective film, and a light-transmissive member. The light emitting element emits first light. The phosphor layer is provided on a light-emitting surface of the light-emitting element, and contains a phosphor being excited by the first light to emit second light with a wavelength longer than a wavelength of the first light. The reflective film is provided on the phosphor layer, reflects the first light, and transmits the second light. The light-transmissive member is in contact with the reflective film.
