A mask for covering part of the surface of the material to be coated comprises an aluminum foil, and a film of a resin provided on one surface of the foil and having a high power of adhering to the foil and any film of paint formed on the resin film. The film of paint which is formed on the resin film when the paint applied to the material to be coated is baked in an oven does not peel off and contaminate the interior of the oven. No such paint film peels off and adheres to the coated surface of the coated product, either, but the mask ensures the improved quality of the coated surface.
