Abstract
Abstract In this invention, a method of manufacturing a colored metallic sheet comprises steps of holding a surface to be painted of metallic plates 10 in a fluorine- or fluoride-containing atmosphere in a heated condition to form a fluorided layer on the surface to be painted, removing the formed fluorided layer on the surface just before painting the surface to expose a metallic base, and painting the exposed metallic base surface.
