| titleOfInvention | Manufacturing method of chemical conversion steel sheet |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a chemical conversion-treated steel sheet having excellent coating adhesion. SOLUTION: An oxolate of a group 4 metal, an ammonium compound, and a group 4 metal are used with respect to a Zn-based plated steel sheet having a Zn-based plated layer of the chemical conversion-treated steel sheet according to the embodiment of the present invention on the surface of a base steel sheet. A coating step of applying a chemical conversion treatment liquid containing a phosphate and a phosphate containing no Group 4 metal, and heating to heat-dry the chemical conversion treatment liquid to form a chemical conversion treatment film on the surface of a Zn-based plated steel plate. Including a drying step. When the atomic ratio of nitrogen in the chemical conversion treatment liquid is X and the atomic ratio of group 4 metal is Y, X / (X + Y) is 0.15 to 0.35.
