Abstract
A method of manufacturing a light emitting element includes forming an n-side electrode at a lateral surface of an n-type semiconductor layer so as not to cover a light extraction surface. Using a portion of a silicon substrate left on an n-type semiconductor layer as a mask, an insulating film formed at a lateral surface of a semiconductor layered body is removed, to expose a lateral surface of the n-type semiconductor layer and a lateral surface of a resin layer. An n-side electrode positioned between the lateral surface of the n-type semiconductor layer and the lateral surface of the resin layer and connected to the exposed lateral surface of the n-type semiconductor layer is formed. Thereafter, the portion of the silicon substrate is removed, to expose the n-type semiconductor layer.
