Abstract
A semiconductor light-emitting device has a semiconductor light-emitting element mounted on an electrode formed on a surface of an insulating substrate and has a reflective case provided on the insulating substrate so as to reflect the light from the light-emitting element with the space inside the reflective case sealed with a translucent resin The reflective case has a grained portion formed over at least part of the surface thereof over which it makes contact with the translucent resin This effectively prevents the translucent resin from coming off the reflective case. To enable the semiconductor light-emitting device to emit light with more even intensity in all directions, the grained portion is formed, preferably, at least in the portions of the reflective case that face the side surfaces of the semiconductor light-emitting element.
