Patent ID: 8395173

Claim:
A semiconductor light-emitting element, comprising: a light-emitting layer having a laminated structure in which a p-type GaN film and an n-type GaN film are included; a conductive hexagonal pyramidal base formed from ZnO and mounted with the light-emitting layer on a bottom surface thereof; an anode joined to the bottom surface of the base at a position apart from the light-emitting layer; and a cathode mounted on the light-emitting layer, wherein the p-type GaN film is joined to the bottom surface of the base, the cathode is joined to an N-polar plane of the n-type GaN film, said N-polar plane being an opposite side to the p-type GaN film, and the N-polar plane of the n-type GaN film has a fine peak-valley structure outside a portion joined to the cathode, said N-polar plane being said opposite side to the p-type GaN film.
