ABSTRACT:
A steel strip having an excellent phosphate-coating property is produced by subjecting at least one surface of the steel strip to electrolytic treatment in which the steel strip serves as an anode and the steel strip surface is brought into contact with an aqueous solution containing at least one phosphate selected from the group consisting of alkali metal phosphates and ammonium phosphate and having a concentration of phosphoric anions of 0.05 mole/l or more and a pH of from 4 to 7, at an anode current density of 2 A/dm.sup.2 or more, to an extent that a phosphate surface layer is formed in an amount of 0.0001 to 0.05 g/m.sup.2 on the metal strip surface.
