Abstract:
1. A flip chip type light-emitting element, comprising: a III-group nitride semiconductor layer comprising an n layer, a p layer and an active layer formed between the n layer and the p layer, the n layer being exposed in a comb-tooth shape; an n type contact electrode provided on the n layer; a light transmission electrode provided on the p layer; a plurality of pad electrodes provided on the light transmission electrode; an insulating protective film that covers a surface of the III-group nitride semiconductor layer except a part of the pad electrodes; and a reflecting film provided above the light transmission electrode and in the insulating protective film so as to reflect a light emitted from the active layer to a side of the n layer, wherein at least one of the plurality of pad electrodes comprises a base part that is not covered with the insulating protective film, and a plurality of branch parts that is formed from the base part, and wherein the base part is connected to a junction electrode provided above the reflecting film.
