A semiconductor element is disclosed having a layered body of a first conductivity type, a light emitting layer, a layered body of a second conductivity type, a constriction layer having a constriction hole, and a first electrode having a lighting hole, a second electrode positioned such that charge traveling between the first and second electrodes passes through the light emitting layer. The constriction hole area is larger than the lighting hole area, and the lighting hole and the constriction hole expose a part of the layered body of the second conductivity type. A mirror is positioned such that the mirror receives light emitted from the light emitting layer that passes through the layered body of the first conductivity type, and the mirror is constructed to have a high reflection ratio for light having peak wavelengths between 200 nm to 350 nm.
