Abstract
A semiconductor light emitting element includes a semiconductor multilayer structure including a first conductive type layer, a second conductive type layer, and a light emitting layer sandwiched between the first conductive type layer and the second conductive type layer, and a reflecting layer formed on the second conductive type layer for reflecting the light emitted from the light emitting layer. The light is extracted in a direction from the light emitting layer toward the first conductive type layer. The first conductive type layer includes a concavo-convex region on a surface thereof not opposite to the light emitting layer, for changing a path of light, and at least a part of the reflecting layer is formed extending to right above an edge of the concavo-convex region.
