Abstract
A solid electrolyte membrane is disposed between an anode and a substrate, and voltage is applied between the anode and the substrate while the solid electrolyte membrane is pressed onto the substrate so as to form a metal film on the substrate. In this film forming method, there is used the solid electrolyte membrane that includes: a first portion made of an ion permeable material; and a second portion made of a material having an electric insulating property and having a low permeability of metallic ions, the second portion being embedded in the first portion so as to be exposed from a surface of the solid electrolyte membrane, the surface of the solid electrolyte membrane facing the substrate.
