Abstract

See full text

A method of producing a surface-treated steel sheet is provided. The surface-treated steel sheet includes a layer that contains a metal oxide. The method is characterized by including: dipping a steel sheet for 0.1 to 10 seconds in a treatment liquid that contains at least fluoride ions and has a pH of 2 to 5; and electrically treating by flowing a direct current between the steel sheet and an electrode in a treatment liquid to form a layer that contains a metal oxide on a surface of the steel sheet. According to the present invention, there can be provided a method of producing a surface-treated steel sheet which can enhance the interfacial adhesion with an organic resin layer when the organic resin layer is formed on the metal oxide layer.
