Abstract
A semiconductor light emitting device is provided which allows emission light from a light source to efficiently outgo from the semiconductor light emitting device so that the light emission intensity of the semiconductor light emitting device is increased. A penetrating opening is formed in the substantially central part of a cap member to communicate the interior side to the exterior side the cap member. The penetrating opening has an inclined portion. The inclined portion is opposed to and spaced away from a semiconductor light emitting element and includes a light entering portion through which emission light from the semiconductor light emitting element passes. The opening width of the inclined portion is getting wider from the light entering portion in the light traveling direction so that the inclined portion is tapered. The emission light from the semiconductor light emitting element can effectively outgo from the semiconductor light emitting device.
