A light-emitting element with improved reliability, a light-emitting element package, and a lighting device including the package are provided. A light emitting device according to an embodiment includes a substrate, a light emitting structure including a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer disposed under the substrate, and a second conductive type semiconductor layer. And a reflective layer having at least one first through hole formed in a first direction which is a thickness direction of the light emitting structure, the reflective layer, the second conductive semiconductor layer, and the active layer A contact layer embedded in at least one second through-hole and connected to the first conductive type semiconductor layer, and disposed between each of the reflective layer, the second conductive type semiconductor layer, and the active layer and the contact layer; And an insulating layer embedded in one through hole.
