Abstract:
A method of manufacturing a light-emitting element includes forming a light-transmissive insulating film on a portion of an upper surface of a semiconductor layered body; forming a first light-transmissive electrode to continuously cover the upper surface of the semiconductor layered body and an upper surface of the light-transmissive insulating film; heat-treating the first light-transmissive electrode, and subsequently forming a metal film in at least a portion of a region above the light-transmissive insulating film; forming a second light-transmissive electrode to continuously cover an upper surface of the metal film and an upper surface of the first light-transmissive electrode, the second light-transmissive electrode being electrically connected to the first light-transmissive electrode; and forming a pad electrode in a region where the metal film is disposed in a top view, such that at least a portion of the pad electrode is in contact with an upper surface of the second light-transmissive electrode.
