Claim:
1. A film formation apparatus for forming a metal film, comprising at least: an anode; a solid electrolyte membrane disposed between the anode and a substrate serving as a cathode such that a solution containing metal ions contacts the anode side of the solid electrolyte membrane; and a power supply portion adapted to apply a voltage across the anode and the substrate, wherein a voltage is applied across the anode and the substrate by the power supply portion to deposit metal out of the metal ions contained in the solid electrolyte membrane onto a surface of the substrate, thereby forming a metal film made of the metal, and the anode has a base material and a metal plating film formed over the base material, the base material being insoluble in the solution, and the metal plating film being made of the same metal as the metal film to be formed.
