Abstract
A nitride semiconductor light-emitting element outputs ultraviolet light. The nitride semiconductor light-emitting element includes an active layer including a quantum well structure that generates the ultraviolet light, a dislocation suppression structure-containing layer being formed on the active layer and including a dislocation suppression structure that stops or bends a dislocation from the active layer; and a p-type contact layer being formed on the dislocation suppression structure-containing layer and having a thickness of not less than 10 nm and not more than 30 nm.
