Disclosed is a method for producing a surface-treated metal material, which comprises a step for treating the surface of a metal material with a treatment liquid (1) containing 10-10,000 ppm of tin ions and having a pH of not less than 1.0, and a step for subjecting the metal material surface-treated with the treatment liquid (1) to a chemical conversion by a treatment liquid (2) containing zirconium ions and/or titanium ions. L'invention porte sur un procédé pour produire un matériau métallique traité en surface, qui comprend une étape consistant à traiter la surface d'un matériau métallique avec un liquide de traitement (1) contenant de 10 à 10.000 ppm d'ions étain et ayant un pH qui n'est pas inférieur à 1,0 et une étape consistant à soumettre le matériau métallique traité en surface avec le liquide de traitement (1) à une conversion chimique par un liquide de traitement (2) contenant des ions zirconium et/ou des ions titane.
