Abstract: A zinciferous plated steel sheet which comprises a steel sheet, at least one zinciferous plating layer formed on at least one surface of the steel sheet, and an Fe--Ni--O film as an uppermost layer formed on the zinciferous plating layer. The total quantity of metallic elements in the Fe--Ni--O film is within a range of from 10 to 1,500 mg/m.sup.2, and the oxygen content in the Fe--Ni--O film is within a range of from 0.5 to under 30 wt. %. The ratio of the iron content (g/l) relative to the total quantity of the iron content (g/l) and the nickel content (g/l) in the Fe--Ni--O film is preferably within a range of from over 0 to under 1.0.
