Abstract

A manufacturing method for steel sheets for containers produces steel sheets with excellent film adhesion qualities. In a method for manufacturing steel sheets upon which is formed a chemical conversion coating having a metal Zr content of 1-100 mg/mand F content of no more than 0.1 mg/m, the chemical conversion coating is formed on the steel sheet by subjecting the steel sheet to immersion in or electrolytic treatment with a treatment solution containing Zr ions and F ions, and subsequently, the steel sheet upon which the chemical conversion coating has been formed is washed with water having a temperature of at least 80° C. and dried.
