    摘要: Quaternary ammonium salt having at least one alkyl group of 10 to 20 in carbon number is added to a chemical conversion solution to be at least 20 ppm in concentration, and a chemical conversion coating is formed on a surface of a metal can with this chemical conversion solution. After the chemical conversion coating is formed on the surface of the metal can with the chemical conversion solution, a surface treatment solution containing quaternary ammonium salt having at least one alkyl group of 10 to 20 in carbon number is applied to the surface of the metal can provided with the chemical conversion coating.
