PURPOSE:To make water resistance ana chemical resistance favorable and to prevent generation of a crack, by a method wherein a resin composition containing polyaryl ether ketone having a specific repeating unit and polyaryl other sulfone having a repeating unit is laminated on the surface of a metal body, on which undercoating treatment or metallizing treatment has been performed. CONSTITUTION:A resin composition containing polyaryl ether ketone having a repeating unit as shown by a formula I or II and polyaryl ether sulfone having a repeating unit as shown by a formula III is laminated on the surface of a metal body, on which undercoating treatment or metallizing treatment has been performed. It may be good even if a small quantity of copolymer ingredients of the polyaryl ether ketone or polyaryl ether sulfone has been copolymerized. Then it is preferable that the polyaryl ether ketone and polyaryl ether sulfone are 1:9-9:1 at their weight ratio. Then it is preferable that the above-mentioned resin composition is laminated through baking after the same has been applied to the surface of a metal body, on which undercoating treatment or metallizing treatment has been performed, by a powder coating application method.
