A film with excellent corrosion resistance, alkali resistance, solvent resistance, and fingerprint resistance can be obtained by treating the surface of a metallic material with a water-based surface treatment agent comprised of a specified water-soluble resin or water-based emulsion resin such as a cationic or nonionic urethane, acrylic, epoxy, polyester, or polyamide resin, a phenolic resin-type compound with a specified structure, and a metal compound containing at least one metal selected from the group consisting of Zr, Ti, V, Mo, W, Mn, and Ce.
