Abstract:
1. A semiconductor light-emitting element comprising: a first semiconductor layer that is composed of a group-III nitride semiconductor having a first conductivity type; a light-emitting layer that is laminated on one surface of the first semiconductor layer to expose a part of the one surface, and that emits light upon conducting an electric power; a second semiconductor layer that is composed of a group-III nitride semiconductor having a second conductivity type different from the first conductivity type, and that is laminated on the light-emitting layer; a first transparent conductive layer that is composed of a material having transparency to light emitted from the light-emitting layer and a conductive property, and that is laminated on the second semiconductor layer; a transparent insulating layer that is composed of a material having transparency to the light emitted from the light-emitting layer and an insulating property, that has a penetration hole in a thickness direction, and that is laminated on the first transparent conductive layer; a first electrode that is electrically connected to the first semiconductor layer; and a second electrode that is configured with a second transparent conductive layer and a metal reflective layer, the second transparent conductive layer being composed of a material same as the material of the first transparent conductive layer and laminated to cover the transparent insulating layer and the first transparent conductive layer exposed through the penetration hole, the metal reflective layer being composed of a metal material having reflectance to the light emitted from the light-emitting layer and a conductive property and laminated on the second transparent conductive layer, wherein at least a part of the second transparent conductive layer contacts the first transparent conductive layer.
