SEMICONDUCTOR LIGHT-EMITTING ELEMENT

PROBLEM TO BE SOLVED: To improve light extraction efficiency of a semiconductor light-emitting element.SOLUTION: A light-emitting structure 10 bonded to a support structure 20 via bonding layers 180, 220 includes: a first reflection part which is disposed on the bonding layers 180, 220 and is provided with a reflection layer made of a metal material; a semiconductor lamination part 10s which is disposed on the first reflection part and is provided with a light-emitting layer 142; and an electrode disposed on part of that surface of a first conductivity type clad layer which serves as a light extraction surface. The semiconductor lamination part 10s is provided with a second reflection part in which two or more semiconductor layers having different refractive indices are laminated, between the electrode and the first conductivity type clad layer. A third reflection part made of a metal material is provided on a side surface of the second reflection part.
