A coated metal sheet has undercoat and topcoat paint films formed on the metal substrate. The undercoat film is composed of polyester paint, which is preferably prepared by adding methylated or butylated melamine resin as a curing agent to hydroxyl group-containing macromolecular polyester resin having a glass-transition temperature of 10.degree. C. or higher. The topcoat film is composed of the polyester paint which is preferably prepared by adding an isocyanate curing agent in an amount of 10 wt. % or more to hydrocyl group-containing macromolecular polyester resin. The substrate metal may be a chemically converted steel sheet, galvarnized steel sheet, stainless steel sheet or aluminum sheet. Since the coated steel sheet is bonded with excellent shear strength and durability, it is useful as the casing of electric home appliance or business machine, or a structural member or part for building or furniture.
