1. A method for producing a surface-treated steel sheet comprising:
forming a phosphate compound layer on a tin-plated steel sheet by means of an anode electrolytic treatment, wherein the tin-plated steel sheet is obtained by tin-plating a steel sheet; and
forming an aluminum-oxygen compound layer on the phosphate compound layer by means of an electrolytic treatment using an electrolytic treatment liquid containing aluminum.
