Abstract
A group III nitride semiconductor light-emitting element includes a single crystal substrate and an element layer. The element layer includes an n-type layer, an active layer, and a p-type layer formed on the upper surface of the single crystal substrate in this order, and has a composition represented by the composition formula AlGaInN (0≤X≤1.0, 0≤Y≤1.0, 0≤X+Y≤1.0). The thickness of the single crystal substrate is at least 80 μm. The area of the upper surface of the substrate is larger than the area of the bottom surface of the substrate.
