An object of the present invention is to provide a light emitting device with excellent light extraction efficiency due to reduced self-absorption of light from the light emitting element. The inventive light emitting device comprises a board, a semiconductor light emitting element formed on the board optionally via a submount, a cap sealing the semiconductor light emitting element and a reflector provided surrounding the cap, wherein the cap has top and bottom surfaces that are parallel to the top surface of the semiconductor light emitting element, and the spacing between the top and bottom surfaces is 1-3 times the longest diagonal or the diameter of the semiconductor light emitting element. |
