Abstract: A light-emitting diode (10) has a light-extracting surface and includes a transparent substrate (14), a compound semiconductor layer (13) bonded to the transparent substrate, a light-emitting part (12) contained in the compound semiconductor layer, a light-emitting layer (133) contained in the light-emitting part and formed of (AlXGa1-X)YIn1-YP(0?X?1, 0<Y?1), first and second electrodes (15, 16) of different polarities provided on a surface of the light-emitting diode opposite the light-extracting surface, and a reflecting metal film (17) formed on the first electrode. The transparent substrate has a first side face (142) virtually perpendicular to a light-emitting surface of the light-emitting layer on a side near the light-emitting layer and a second side face (143) oblique to the light-emitting surface on a side distant from the light-emitting layer. The first and second electrodes are mounted respectively on electrode terminals (43, 44).
