Abstract:
A light-emitting element includes: a semiconductor stacked body; an insulating film located on a p-type semiconductor layer; a p-side electrode located on the insulating film, the p-side electrode comprising a pad portion and an extension portion, the extension portion being continuous with the pad portion in a first direction; a light-transmissive conductive film located on the p-type semiconductor layer and on the insulating film, the light-transmissive conductive film having an opening that is continuous along the extension portion on the insulating film; and a reflective film located between the insulating film and the p-side electrode in the opening. The opening includes a first opening and a second opening. In the second direction, the light-transmissive conductive film is electrically connected to the extension portion of the p-side electrode at a portion adjacent to a region where the first opening is located.
