Abstract
A group-III nitride compound semiconductor light emitting element includes a substrate that has a main face on which an concave and convex portion is formed, a group-III nitride compound semiconductor layer that is formed on the main face of the substrate, and a clearance that is formed between the substrate and the group-III nitride compound semiconductor layer at a first region of the semiconductor light emitting element. In the first region, a portion of the group-III nitride compound semiconductor layer and a portion of the clearance are disposed in a concave of the concave and convex portion on a section through two adjacent top portions of the concave and convex portion and a bottom portion located between the adjacent top portions.
