Abstract
The present disclosure relates to a film-forming metal solution for use in a method in which a solid electrolyte membrane having sulfonic acid groups is disposed between an anode and a substrate serving as a cathode, the solid electrolyte membrane is brought into contact with the substrate, and a voltage is applied between the anode and the substrate to deposit a metal onto a surface of the substrate from metal ions supplied into the solid electrolyte membrane and thereby form a metal coating on the surface of the substrate, the film-forming metal solution being adapted to supply metal ions into the solid electrolyte membrane, wherein the film-forming metal solution comprises an aqueous metal solution, a solvent, and a nonionic surfactant, and the nonionic surfactant has a linear hydrophilic group having ethylene oxide units and a hydrophobic group having a cyclic structure and a maximum length of 40 Å or less.
