摘要： A method of forming a metal coating includes: disposing a solid electrolyte membrane (13) between an anode (11) and a substrate (B) which forms a cathode; bringing a solution (L) containing metal ions into contact with an anode-side portion of the solid electrolyte membrane (13); and causing, in a state where the solid electrolyte membrane (13) is in contact with the substrate (B), a current to flow from the anode (11) to the cathode so as to form a metal coating formed of the metal on the surface of the substrate (B). The metal coating is formed by repeating a current-flowing period (T) in which a current flows from the anode (11) to the cathode and a non-current-flowing period (N) in which a current does not flow between the anode (11) and the cathode.

A film formation apparatus includes an anode (11); a solid electrolyte membrane (13) disposed between the anode and a substrate (B) serving as a cathode such that a metal ion solution (L) is disposed on the anode (11) side thereof; and a power supply portion (14) adapted to apply a voltage across the anode (11) and the substrate (B). A voltage is applied across the anode (11) and the substrate (B) to deposit metal out of the metal ions contained in the solid electrolyte membrane (13) onto the surface of the substrate (B), thereby forming a metal film (F) made of the metal of the metal ions. The anode (11) has a base material (11a), which is insoluble in the metal ion solution (L), and a metal plating film (11c), which is made of the same metal as the metal film (F), formed over the base material (11a).
