PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting element which achieves more improved light-extraction efficiency.SOLUTION: A semiconductor light-emitting element includes an n-type nitride semiconductor layer, a luminescent layer and a p-type nitride semiconductor layer which are stacked in this order on a substrate having a plurality of salients on a surface. The n-type nitride semiconductor layer has an exposed region extending in one direction at least in a partial region. A bottom face of the salient has a shape having a plurality of apexes. The salients among the plurality of salients, which are arranged such that two adjacent apexes have minimal lengths and equal distances from an extended line extending in the one direction including the exposed region, constitute more than half of the whole. |
