  • Electromagnetic wave-shielding construction material and method for producing the same
    Publication number: 20020164458
    Abstract: The main object of the present invention is to provide an electromagnetic wave-shielding construction material which can cut-off electromagnetic waves at low costs in an efficient manner and a method for the production of the electromagnetic wave-shielding construction material. In order to achieve the above-mentioned object, the present invention provides an electromagnetic wave-shielding construction material comprising laminating an electromagnetic wave-shielding sheet, prepared by forming a conductive ink layer on one surface of a base material sheet by printing, on at least one plate surface of a panel section formed of a mixed material consisting of major panel components and a conductive material such that the conductive ink layer is in contact with the plate surface.
