PURPOSE:To obtain a thermoplastic resin having improved moldability and excellent electromagnetic wave shielding properties, by interposing a metallic fiber between thermoplastic resin sheets, molding them by heating, cutting the molding into pellets and blending the pellets with a thermoplastic resin. CONSTITUTION:A metallic fiber having a fiber diameter of pref. 4-20mu is interposed between thermoplastic resin sheets and the laminate is molded by heating. The resulting molding is cut into pellets, which are blended with a thermoplastic resin, pref. polypropylene to obtain an electromagnetic wave shielding resin. The metallic fiber is used in a quantity of pref. 80-120pts.wt. per 100pts.wt. thermoplastic resin. Pref. the pellet should have nearly the same size as that of the thermoplastic resin pellet from the viewpoint of excellent moldability, and is to be cut into such a length that the metallic fiber has a length of 1-10mm..
