To provide a board in which an electromagnetic wave shielding effect is provided to a board itself, and heating performance and antifungal properties are also held, and further which is favorable in points of weight and cost.

An electromagnetic wave shielding board, molded in a body by bonding a mesh-like electromagnetic wave shielding fiber 2 to the surface of a plaster material 1, and laminating another plaster material 3 containing anti-fungus agent on the electromagnetic wave shielding fiber 2, is employed as a basic structure. A hard plaster is used as one plaster material 1, and soft plaster is used as the another plaster material 3. Further, an example in which the mesh-like electromagnetic wave shielding fiber 2 and a mat-like glass fiber 4 are bonded on the surface of the plaster material, an example in which the electromagnetic wave shielding fiber 2 and a heater 5 for electric heat are bonded, and a constitution of the electromagnetic wave shielding board molded in a body by bonding all of the glass fiber 4 and the heater 5 for electric heat to the electromagnetic wave shielding fiber 2, and laminating the other plaster material 3, are provided.
