Abstract
A nitride semiconductor template includes a substrate, an AlN layer that is formed on the substrate and that includes Cl, and a nitride semiconductor layer formed on the AlN layer. In the AlN layer, a concentration of the Cl in a region on a side of the substrate is higher than that in a region on a side of the nitride semiconductor layer. Also, a light-emitting element includes the nitride semiconductor template, and a light-emitting layer formed on the nitride semiconductor template.
