Method for producing surface-treated steel sheet, surface-treated steel sheet, and organic resin coated metal container
Provided is a method for producing a surface-treated steel sheet including the step of forming a layer mainly composed of an oxygen compound containing Al onto a tin-plated steel sheet by conducting cathode electrolytic treatment to the tin-plated steel sheet using an electrolytic treatment solution containing Al ions and nitrate ions. For the electrolytic treatment solution, an electrolytic treatment solution not containing F ions and where the amount of nitrate ions contained is 11,500 to 25,000 ppm by weight is used.
