PROBLEM TO BE SOLVED: To provide a method of manufacturing a stain prevention mat for electromagnetic cooker such that a heat-resistive coat material is not struck through, and the stain prevention mat for electromagnetic cooker.SOLUTION: The stain prevention map which is used while put between a top plate of an electromagnetic cooker and a bottom surface of a pan heated by the electromagnetic cooker includes a glass fiber sheet 5, a first coat material covering one surface of the glass fiber sheet 5, and a second coat material covering the other surface. The glass fiber sheet 5 is made less in air permeability than a conventional glass fiber sheet by narrowing down area of gaps 6 between general glass fibers 3 and 4, which transmit lines of magnetic force and have heat resistance, in plan view by widening widths of the glass fibers 3 and 4 by pressing glass fiber cloth formed by plain weaving of pluralities of general glass fibers 3 and 4 with a water flow (water flow processing). Consequently, the first coat material applied over one surface of the glass fiber sheet 5 is not struck through as compared with a conventional one having the same basis weight. |
