PURPOSE:To simplify the manufacturing process, to provide a radio wave reflecting performance and to maintain the performance for a long period by laminating sequentially a thermoplastic resin layer with excellent wheather resistance, a metallic layer reflecting a radio wave and a polyamide resin layer incorporating an inorganic poacking agent. CONSTITUTION:The thermoplastic resin layer 3 formed with a thickness of 5mu- 5mm. prevents corrosion of the metallic layer 2. The metallic layer 2, formed with a thickness of 5mu-1mm., reflects a radio wave. The ratio of composition of the inorganic packing agent in the polyamide layer 1 incorporating the inorganic packing agent is 10-80wt% and its thickness is 0.5-15mm.. Then the resin layer 3, the metallic layer 2 and the polyamide layer 1 are laminated sequentially. |
