Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composition for treating the surface of a metal, which can form a film that can impart superior corrosion resistance to a metal material, particularly a metal structural body having a complicated shape, in a single immersion step. SOLUTION: The composition for treating the surface of a metal includes 5-30 wt.% of a nonionic and/or cationic water-based resin, 100-1,000 ppm of a trivalent Bi ion, and an amino polycarboxylic acid in a molar concentration of 0.5-10 times with respect to that of the Bi ion.
