Abstract: The coating film-forming composition is a solution of pH 6 to 9 and includes an aromatic compound having an amino group and an aromatic ring in one molecule, a polybasic acid having two or more carboxy groups, and a halide ion. The content of polybasic acid in the coating film-forming composition is 0.05 to 10 times the content of aromatic compound, and the halide ion concentration is 5 to 600 mM. A coating film with excellent adhesion to a resin can be formed on a surface of a metal member by bringing the coating film-forming composition into contact with the surface of the metal member.
