Abstract

This chemical conversion-treated steel sheet () has a chemical conversion treatment coating () upon a plating layer () of a steel sheet (). The chemical conversion treatment coating () contains a fluororesin, a base resin which is a resin other than a fluororesin, metal flakes (), and a chemical conversion treatment component. The content of the fluororesin in relation to the total quantity of resins is 3.0 mass % or more in terms of fluorine atoms, the content of the base resin in relation to 100 parts by mass of the fluororesin is 10 parts by mass or more, and the content of metal flakes () in the chemical conversion treatment coating () is more than 20 mass % but at most 60 mass %.
