Abstract
An excellent light emitting element capable of improving problems caused by a material having high light-reflectivity and susceptible to electromigration, especially Al used for the electrode. FIG. 2A depicts semiconductor light emitting element having a first and second electrodes 20 and 30 disposed at a same surface side respectively on a first and second conductive type semiconductor layer 11 and 13. In the electrode disposing surface, the first electrode 20 comprises a first base part 23 and a first extended part 24 extending from the first base part, and a plurality of separated external connecting parts 31 of the second electrode 30 arranged side by side in extending direction of the first extended part.
