Abstract
A nitride semiconductor light emitting element includes a light emitting layer. The light emitting layer includes an InGaN well layer (0<x≦1) having a principal surface that is an m-plane. A profile in a depth direction (depth profile) of an In composition ratio x in the InGaN well layer has a plurality of peaks. Values of the In composition ratios x at the respective plurality of peaks are different from one another.
