Abstract
A semiconductor light-emitting element according to the present invention is a semiconductor light-emitting element including: a first semiconductor layer of a first conductivity type; a light-emitting functional layer formed on the first semiconductor layer; and a second semiconductor layer that is formed on the light-emitting functional layer and is of a second conductivity type opposite to that of the first semiconductor layer. The light-emitting functional layer has: a base layer formed on the first semiconductor layer, the base layer having a plurality of base segments that have a composition subject to stress strain from the first semiconductor layer and are formed in a random net shape, the base layer being doped with a dopant of the second conductivity type; and a quantum well light-emitting layer formed on the base layer.
