摘要： 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.

摘要： A method of producing a surface-treated steel sheet is provided. The method has a step of performing electrolytic treatment thereby to form a layer including a metal-oxygen compound on a surface of a steel sheet. The electrolytic treatment is performed so that the steel sheet is continuously fed into electrolytic treatment baths each including a treatment liquid and an electrode. The treatment liquid contains metal ions. The method is characterized in that: rolls provided for each of the electrolytic treatment baths (a roll for feeding the steel sheet into the electrolytic treatment bath and a roll for feeding the steel sheet out of the electrolytic treatment bath) comprise an energized roll that is electrically connected to a power source for flowing a direct current through the steel sheet and a non-energized roll that is not connected to a power source; and the energized roll is arranged such that, once the metal-oxygen compound has been formed by electrolytic treatment on a surface of the steel sheet to be in contact with the rolls, the metal-oxygen compound and the energized roll are not in contact with each other so as not to generate an arc spot.
