A thin-layer metal film that is high in productivity, can be prepared in a simple step, has a high density, and is superior in durability. The thin-layer metal film is obtained by reducing a metal salt on a surface of a substrate where a metal salt-containing hydrophilic graft polymer chain is present. The thin-layer metal film is obtained by reducing a metal ion adsorbed on a hydrophilic functional group of the hydrophilic graft polymer chain with a reducing agent to deposit a metal. |
