Claim Text:
1. A semiconductor light emitting element comprising: a semiconductor laminated body in which an n-type semiconductor layer and a p-type semiconductor layer are laminated; a first metal film that is provided on an upper surface of the p-type semiconductor layer and of which a surface contacting on the p-type semiconductor layer is made of an Ag or an Ag-based alloy; a second metal film that covers a surface of the first metal film, is provided to contact on the upper surface of the p-type semiconductor layer at an outer edge of the first metal film, has a concave part on an upper surface of the second metal film, and is made of an Al or an Al-based alloy, wherein the concave part has a bottom surface and lateral surfaces; a third metal film that is provided in the concave part formed in the second metal film, and is in contact with the bottom surface of the concave part in the second metal film; a metal oxide film that covers other portions of the second metal film and contains at least an oxide of a metal material forming the second metal film; and an insulation film that covers a surface of the metal oxide film and is made of an oxide.
