A semiconductor light emitting element having a rectangular shape in plan view comprising at least a first side and a second side adjacent to the first side, the semiconductor light emitting element including a first conductivity-type semiconductor layer, a second conductivity-type semiconductor layer, a plurality of first electrodes having a long shape along the first side and being arranged on the first conductivity-type semiconductor layer in a lattice form of x columns (x≧2) along the first side and y rows (y>x) along the second side, and a second electrode arranged on the second conductivity-type semiconductor layer. The first electrode and the second electrode are arranged on the same surface side. The first electrode is surrounded by the first conductivity-type semiconductor layer, the second conductivity-type semiconductor layer, and the second electrode is provided.
