PROBLEM TO BE SOLVED: To permeate gas from the base material that outgas is easily generated and to hold the metal external appearance without bulge or peel by incorporating fluorine-containing resin in a base layer and incorporating tin in a metal thin film layer. SOLUTION: A metal thin film layer containing tin is laminated on a base layer containing fluorine-containing resin. That is, the metal thin film layer 2 is laminated on the base layer 1, and an adhesive layer 3 is provided. The fluorine-containing resin includes, for example, polymer such as vinyl fluoride, vinylidene fluoride, trifluochloroethylene, tetrafluoroethylene, and ethylene tetrafluoroethylene copolymer, tetrafluoroethylene-propylene hexafluoride copolymer. The thickness of the base layer is preferably about 10 to 200μm. The layer 1 may contain dye or pigment to be colored, and in this case, it is transparent or translucent. If it is opaque, the gloss of the metal thin film layer cannot be obtained. |
