ABSTRACT OF THE DISCLOSURE There is provided an FRP molded article having the properties of uniformly reflecting and shielding electro- magnetic waves in the range of VHF to EHF. The molded article comprises a compression-molded laminated structure composed of an electroconductive nonwoven fabric-resin composite surface layer, a woven fabric-resin composite intermediate layer, and a fiber material reinforced resin substrate layer. The molded article can be produced by placing, on a mold, an electroconductive nonwoven fabric or a prepreg thereof, a woven fabric or a prepreg thereof, and then a mixture of a reinforcing fiber material and a liquid crosslink-curable resin composition thereon, and subjecting the laminated materials to compression molding. The molded articles can be advantageously used, for example, as reflect- ing dish antennas as well as shielding sheets or boards for electromagnetic waves.
