Abstract
A semiconductor light-emitting element includes a semiconductor laminated structure including a light-emitting layer sandwiched between first and second conductivity type layers for extracting an emitted light from the light-emitting layer on a side of the second conductivity type layer, a transparent electrode in ohmic contact with the second conductivity type layer, an insulation layer formed on the transparent electrode, an upper electrode for wire bonding formed on the insulation layer, a lower electrode that penetrates the insulation layer, is in ohmic contact with the transparent electrode and the electrode for wire bonding, and has an area smaller than that of the upper electrode in top view, and a reflective portion for reflecting at least a portion of light transmitted through a region of the transparent electrode not in contact with the lower electrode.
