Abstract
A first semiconductor element (laser diode) and a second semiconductor element (laser diode) are connected to each other in series between a wiring electrically connected to an anode of the first semiconductor element and a wiring electrically connected to a cathode of the second semiconductor element. In this case, each of the first semiconductor element and the second semiconductor element includes a laminated pattern having an emission layer and a plurality of semiconductor layers covering this laminated pattern.
