Abstract

Provided are a film formation device and a film formation method for forming a metal film, with which metal films with a desired thickness can be continuously formed on surfaces of a plurality of substrates. A film formation device 1A includes at least a positive electrode 11, a negative electrode 12, a solid electrolyte membrane 13 arranged on a surface of the positive electrode 12, between. the positive electrode and a substrate to serve as the negative electrode, and a power supply unit E adapted to apply a voltage across the positive electrode 11 and the substrate B. A voltage is applied across the positive electrode 11 and the substrate B to deposit metal on a surface of the substrate from metal ions contained in the solid electrolyte membrane 13, whereby a metal film F made of metal is formed, The positive electrode 11 is made of a porous body that allows a solution L containing metal ions to pass therethrough and supplies the metal ions to the solid electrolyte membrane 13.
