Zusammenfassung:A semiconductor device includes a semiconductor substrate, a metal member, and a metal oxide film. The semiconductor substrate is provided with a through-hole that passes through the semiconductor substrate from one surface to another surface opposite to the one surface. The metal member is provided in the through-hole, and includes a cavity therein defined by an internal surface. The metal oxide film coats the internal surface.
