A n-type layer, a multiquantum well active layer comprising a plurality of pairs of an InGaN well layer/InGaN barrier layer, and a p-type layer are laminated on a substrate to provide a nitride semiconductor light emitting element. A composition of the InGaN barrier included in the multiquantum well active layer is expressed by InxGa1-xN (0.04≦x≦0.1), and a total thickness of InGaN layers comprising an In composition ratio within a range of 0.04 to 0.1 in the light emitting element including the InGaN barrier layers is not greater than 60 nm.
