Abstract
A semiconductor light emitting element suppressing non-uniformity in light emission on a light emitting surface is provided. An n-type semiconductor layer, a light emitting layer and a p-type semiconductor layer are laminated in order, and a translucent electrode film is laminated on the p-type semiconductor layer and a p-electrode is provided on the translucent electrode film. On the other hand, an n-electrode is provided on a semiconductor layer exposure surface that exposes the n-type semiconductor layer. The p-electrode includes a connecting portion having a circular planar shape and an extending portion that extends like a long and slender strip from the connecting portion to encircle and face the n-electrode. Holes in the translucent electrode film are provided such that the density thereof is decreased along with a move from the n-electrode side toward the p-electrode side.
