Abstract

A wiring substrate includes an insulating substrate, a conductor layer and an interlayer. The insulating substrate contains AlN. The conductor layer contains Cu. The interlayer is located between the insulating substrate and the conductor layer. In the interlayer, between a first region near the insulating substrate and a second region near the conductor layer, Cu concentration is higher in the second region than in the first region, and Al concentration is higher in the first region than in the second region.
