Abstract

Provided is a container-use surface treated steel sheet which is manufactured without using chromium and exhibits excellent working adhesion with a coated organic resin, a method of manufacturing the container-use surface treated steel sheet, an organic resin coated surface treated steel sheet. The container-use surface treated steel sheet is a surface treated steel sheet where nickel plating is applied to at least one-side surface of surfaces of a steel sheet by coating, wherein nickel plating has a fine particle shape formed by fine particles which has particle density of 2 to 500 pieces/μmand having an average particle size of 0.05 to 0.7 μm. The container-use surface treated steel sheet is also characterized in that a coating weight of the nickel plating of the container-use surface treated steel sheet is 0.1 to 12 g/m, metal tin is contained in coating of the nickel plating, and an amount of metal tin is 0.05 to 0.1 g/m. The organic-resin-coated surface treated steel sheet of the present invention is characterized in that an organic resin layer is formed on at least one surface of the container-use surface treated steel sheet. The metal can is formed by working the organic-resin-coated surface steel sheet.
