Abstract
A semiconductor surface light-emitting element of this invention is provided with a photonic crystal layerobtained by periodically forming a plurality of holes H in a basic layerA comprised of a first compound semiconductor of the zinc blend structure and growing embedded regionsB comprised of a second compound semiconductor of the zinc blend structure, in the holes H, and an active layerto supply light to the photonic crystal layer, in which a principal surface of the basic layerA is a (001) plane and in which side faces of each hole H have at least three different {100} facets.
