Provided is a nitride semiconductor light emitting element capable of producing an emission spectrum having two peaks with stable ratio of emission peak intensity. The nitride semiconductor light emitting 1 comprises an active layer 12 disposed between an n-type nitride semiconductor layer 11 and a p-type nitride semiconductor layer 13. The active layer 12 comprises a first well layer 14, second well layers 15 interposing the first well layer 14 and disposed at outermost sides among the well layers, and barrier layers 16, 17 disposed between each of the well layers. The second well layer 15 comprises a nitride semiconductor having a larger band gap energy than the band gap energy of a nitride semiconductor constituting the first well layer 14, and the nitride semiconductor light emitting element 1 has peaks in the emission spectrum respectively corresponding to the first well layer 14 and the second well layer 15.
