Abstract
According to one embodiment, a semiconductor light emitting device having a base, a mounting material and a chip of a semiconductor light emitting element is provided. The mounting material is provided on the base. The chip of the semiconductor light emitting element is fixed onto the base via the mounting material. The chip of the semiconductor light emitting element is provided with a sapphire substrate, an active region, a light shielding portion and anode and cathode electrodes for supplying an electric power to the active region. The active region is provided on the sapphire substrate and has a light emitting layer for emitting light by supplying electric power. The light shielding portion is formed on the sapphire substrate on the side of the mounting material. The light shielding portion prevents the mounting material from being irradiated with the light produced in the light emitting layer.
