Abstract:
1. A light-emitting diode element, comprising: a first semiconductor layer of a first conductivity type having a principal surface and a rear surface, the first semiconductor layer being made of a gallium nitride-based compound, the principal surface being an m-plane; a semiconductor multilayer structure provided on a first region of the principal surface of the first semiconductor layer, the semiconductor multilayer structure including a second semiconductor layer of a second conductivity type and an active layer interposed between the first semiconductor layer and the second semiconductor layer; a first electrode provided on the second semiconductor layer; a conductor portion provided on a second region of the principal surface of the first semiconductor layer, the conductor portion being in contact with an inner wall of a through hole penetrating through the first semiconductor layer; and a second electrode provided on the second region of the principal surface of the first semiconductor layer, the second electrode being in contact with the conductor portion, wherein a lateral surface of the inner wall of the through hole includes a c-plane or an a-plane.
