Abstract
The Sn-based alloy plated steel sheet of this disclosure includes: a steel sheet; a composite plating layer formed on at least one side of the steel sheet and including an Fe—Ni—Sn alloy layer and an island-shaped Sn layer located on the Fe—Ni—Sn alloy layer; and a coating layer formed on the surface of the composite plating layer and containing zirconium oxide and tin oxide, and the composite plating layer contains a predetermined amount of Ni and a predetermined amount of Sn, a content of the zirconium oxide in the coating layer is from 0.2 mg/mto 50 mg/min terms of metal Zr amount, and a peak position of binding energy of Sn3daccording to X-ray photoelectron spectroscopy of the tin oxide in the coating layer is 1.6 eV or higher than a peak position of binding energy of the metal Sn.
