Abstract
A semiconductor light device includes a light emitting element, a reflector for reflecting a light beam outgoing from the light emitting element and a resin disposed between the light emitting element and the reflector, which are formed on a substrate. A face of the reflector is formed into a rough surface to improve adherence between the reflector and the resin for preventing detachment of the reflector from the resin.
