Abstract

A light emitting element includes a semiconductor laminated structure including a first semiconductor layer of first conductivity type, a second semiconductor layer of second conductivity type different from the first conductivity type, and an active layer sandwiched between the first semiconductor layer and the second semiconductor layer, a surface electrode including a center electrode disposed on one surface of the semiconductor laminated structure and a thin wire electrode extending from a periphery of the center electrode, and a contact part disposed on a part of another surface of the semiconductor laminated structure extruding a part located directly below the surface electrode, in parallel along the thin wire electrode, and including a plurality of first regions forming the shortest current pathway between the thin wire electrode and a second region allowing the plural first regions to be connected. The surface electrode has an arrangement that the shortest current pathway between the center electrode and the contact part is longer than the shortest current pathway between the thin wire electrode and the first region, and the shortest current pathway between an end part of the thin wire electrode and the contact part is not shorter than the shortest current pathway between the thin wire electrode and the first region.
