Abstract
A light emitting element includes an element main body and a sapphire substrate. The element main body has an AlGaAs-based semiconductor layer, an n-type current diffusion layer, and a cap layer of an InGa-based semiconductor that does not contains As as a component in a lamination direction. The amorphous layer is interposed between the element main body and the sapphire substrate, and contains constituent elements of the cap layer and the sapphire substrate as components.
