Beschreibung
Zusammenfassung:	The present invention provides a novel metal surface treatment agent capable of forming a coating film capable of maintaining antibacterial performance on the surface of a metal material or on the surface, a metal material having a coating film, and a method for producing the metal material. A metal surface treatment agent containing a copolymer (A) obtained by polymerizing a compound (a) represented by formula (1) and a compound (b) represented by formula (2) or formula (3), and a water-soluble or water-dispersible resin (B), the metal surface treatment agent being characterized in that: the ratio [aM: bM] of the molar weight (aM) of the polymerized compound (a) to the molar weight (bM) of the compound (b) ranges from 90: 10 to 20: 80; the copolymer (A) has a weight-average molecular weight of 50,000 or more, the resin (B) is one or more selected from the group consisting of polyurethane resins, polyvinyl alcohol resins, polyamide resins, epoxy resins, phenol resins, and polyvinylpyrrolidone resins, and the
