A nitride semiconductor light-emitting element 300 is a nitride semiconductor light-emitting element which has a multilayer structure 310, the multilayer structure 310 including an active layer which is made of an m-plane nitride semiconductor. The multilayer structure 310 has a light extraction surface 311a which is parallel to an m-plane in the nitride semiconductor active layer 306 and light extraction surfaces 311b which are parallel to a c-plane in the nitride semiconductor active layer 306. The ratio of an area of the light extraction surfaces 311b to an area of the light extraction surface 311a is not more than 46%.
