PROBLEM TO BE SOLVED: To realize a light emitting diode having a large light emitting output and a light emitting diode array. SOLUTION: A light emitting diode 10 is formed by making on a substrate 13 a double hetero structure that both upper and lower surfaces of an active layer 19 as a light emitting part are pinched by clad layers 17 and 21, providing a contact layer 23 on the clad layer on the upper surface of the active layer, and providing an electrode 27 on the contact layer 23. An insulation film 25a is partly interposed between the contact layer 23 and electrode 27, and the electrode 27 and contact layer 23 are electrically connected just thereunder in the peripheral end of the electrode 27 where the insulation film 25a does not exist. |
