Abstract
There are provided a semiconductor light emitting element which allows an improvement in light extraction efficiency without increasing the number of fabrication steps, and a wafer. In a semiconductor light emitting elementformed by laminating a compound semiconductor layeron a single crystal substrate, and dividing the single crystal substrate into pieces, the side facestoof each of substrate piecesas the divided single crystal substrate are formed such that the side faceused as the reference of the substrate pieceforms an angle of 15° with respect to the (1-100) plane, and that the side facestoare formed of planes different from cleaved planes of a crystalline structure in the single crystal substrate.
