Surface Treated Steel Sheet

Abstract: This surface-treated steel sheet comprises a steel sheet, a Zn-based plated layer formed on the steel sheet, and a film formed on the Zn-based plated layer, wherein: the Si concentration, P concentration, F concentration, V concentration, Zr concentration, Zn concentration, and Al concentration in the film are, in terms of mass%, 10.00-25.00% for Si, 0.01-5.00% for P, 0.01-2.00% for F, 0.01-4.00% for V, 0.01-3.00% for Zr, 0-3.00% for Zn, and 0-3.00% for Al; and in a narrow spectrum of Si2p obtained by performing XPS analysis on the surface of the film, the ratio of the integrated intensity of a peak having the maximum value in 103.37±0.25 eV to the integrated intensity of a peak having the maximum value in 102.26±0.25 eV is 0.04-0.25.
