Provided is a metal coating film formation device capable of forming a film using a simple device configuration and in a short time, and capable of performing the formation of a film of metal coating continuously for a long period. A film formation device 1A is provided with an anode 11, a solid electrolyte film 13 disposed between the anode 11 and the base material B, and a power supply unit 16 that applies a voltage between the anode 11 and the base material B. The anode 11 is a non-porous anode comprising the same metal as the metal of the metal coating. Between the anode 11 and the solid electrolyte film 13, a porous material 14 is disposed in contact with the anode 11 and the solid electrolyte film 13. The porous material 14 includes a plurality of pores providing communication between the anode 11 and the solid electrolyte film 13 and being supplied with a metal solution L.
