Abstract
Pellets for making electromagnetic wave shielding material and a method for manufacturing the same are provided in which a desired number of conductive fibers of a desired length are impregnated with thermoplastic resin oligomer to provide an integral unit and then the thermoplastic resin is coated on the outside of the integral unit. The pellets are excellent in a dispersion of the conductive fibers in the thermoplastic resin, greater in aspect ratio, and excellent for use in making a shielding material against electric and magnetic fields.
