In a resin-coated metal sheet, at least one surface of a metal sheet 10 as a base is overlaid by a transparent polyseter resin film A of 5 to 100 mu m thickness, through a paint layer E, a modified olefin resin layer D of 5 to 100 mu m thickness, a pattern or/and solid printing layer C and an adhesive layer B which layers are put one over another in order from side of the metal sheet toward the transparent polyseter resin film. Since the modified olefin resin layer which is provided in between the transparent polyseter resin film and the metal sheet has the excellent adhesiveness against the printing layer, the paint layer and the polyseter resin film, even if the resin-coated metal sheet is formed under the severe condition against the resin-coated metal sheet, for instance by deep drawing, delamination does not occur so that the excellent workable adhesion strength is shown. Further, the roughness of the surface of the metal sheet, and unevenness of several component resin layers are absorbed by a modified olefin resin layer so that the excellent vivid reflectivity for a resin-coated metal sheet can be obtained.
