PROBLEM TO BE SOLVED: To provide a surface-treated metal having excellent environmental properties due to non-chromium surface treatment, and excellent properties such as adhesion to an organic resin film, adhesion, corrosion resistance, dent resistance, scratch resistance, and abrasion resistance. It is to provide a material and a surface treatment method of such a surface-treated metal material. A surface-treated metal material in which a surface-treated layer mainly composed of an inorganic component is formed on a metal surface, wherein the inorganic surface-treated layer contains at least Zr, O, and F as main components, and phosphoric acid. A surface-treated metal material characterized by not containing ions. [Selection] Figure 5 |
