PURPOSE:To make it possible to obtain an electric conductive sheet with permeability between the front side and the rear side by forming metallic evaporation layers on both sides of a base material and also forming the metallic evaporation layers at the inner walls of penetrating holes of the basic material. CONSTITUTION:On both sides of a basic material 1 which furnishes penetrating holes 2, metallic evaporation layers 3 are formed, and at least at some of the penetrating holes, metallic evaporation layer 3 are formed at their inner walls. And the metallic evaporation layers 3 on the front side and the rear side are connected electrically through the penetrating holes 2. Since the metallic evaporation layers 3 are formed at the inner walls 4 of the penetrating holes 2 when the metallic evaporation layers 3 are formed on the both surfaces of the basic material 1, the electric conductibility can be obtained between the front side and the rear side of the basic material 1 through the metallic evaporation layers 3. Furthermore, the electric conductibility can be controlled by the number of the holes 2, the size of the holes 2, the thickness of the metallic evaporation layers 3, and the thickness of the basic material 1, and the air permeability and the slipping property can be also controlled. |
