Abstract
A first principal plane faces a second principal plane of a p-type Ga N compound semiconductor that is in contact with an MQW luminescent layer. On the surface of the first principal plane, a first region made up of the p-type Ga N compound semiconductor including at least Ni is formed. On the surface of the first region, an electrode composed of an alloy including Ni and Aluminum is formed. On the electrode, a pad electrode for external connection consisting of Al or Au is formed.
