Abstract
A highly efficient nitride semiconductor element having an opposed terminal structure, whose terminals face each other. The nitride semiconductor element includes a conductive layer, a first terminal, a nitride semiconductor with a light-emitting layer, and a second terminal, on a supporting substrate successively. The first terminal and a first insulating protect layer are interposed between the conductive layer and a first conductive type nitride semiconductor layer of the nitride semiconductor.
