A semiconductor light emitting element comprising: a plurality of light-emitting-layer forming portions each of which includes a pn junction capable of emitting light of a certain wavelength, and which are separated from one another with a translucent resin formed on the side portions of the light-emitting-layer forming portions; a metal film disposed on first surfaces of the light-emitting-layer forming portions; a conductive substrate bonded to the metal film; a lower electrode formed on a surface of the conductive substrate, the surface being opposite to the surface to which the metal film is bonded; a transparent electrode which is connected to second surfaces, opposite to the first surfaces, of the light-emitting-layer forming portions, and which is substantially transparent to the certain wavelength; and an upper electrode formed above the second surfaces of the light-emitting-layer forming portions with the transparent electrode sandwiched in between.
