A light emitting element includes a first conductivity-type semiconductor layer (3a), a first electrode (10), a second conductivity-type semiconductor layer (3b) and a second electrode (20). The first electrode includes a first connecting portion (11) on a first diagonal line (A-A') and a first extending portion (12) extending from the first connecting portion onto the first diagonal line. The second electrode (20) includes a second connecting portion (21) on the first diagonal line facing the first connecting portion via the first extending portion. Two second extending portions extend from the second connecting portion and having a first portion and a second portion respectively. The first connecting portion (11) includes an end portion (11a) closer to the second connecting portion than a straight line (C-C') intersecting the tip ends (22a, 22b) of the two second extending portions, and a center portion at a side father from the second connecting portion than the second diagonal line (B-B'). This electrode is aiming uniform current distribution and uniform emission over the entire surface of the light emitting element. |
