PURPOSE:To facilitate the patterning of both electrodes when a semiconductor light emitting element array is constituted, by arranging both of the current injection electrodes for semiconductor multilayer structure on the surface side of a substrate. CONSTITUTION:A semiconductor multilayer structure 202 is formed on the surface of a substrate 201, i.e., the upper side surface of the substrate 201. The structure has a junction in the inside, and is constituted so as to radiate light when a current is injected. The form of the semiconductor multilayer structure 202 is rectangular, and a light radiating end surface 204 is formed perpendicularly to the longitudinal direction. A first electrode 203 is stuck to the semiconductor multilayer structure 202, and a second electrode 206 is arranged at the position on the substrate 201 other than the semiconductor multilayer structure 202. When a current is made to flow in the semiconductor multilayer structure 202 by injecting a current from the electrodes 203, 206, light is generated in a junction inside the structure 202. The light can be led out as the radiation light L outputted from the light radiation end surface 204 so as to be vertical to said end surface. Thereby the patterning of electrodes is facilitated. |
