Zusammenfassung:	PURPOSE:To improve the electromagnetic wave shielding effect of moldings, by allowing electrically conductive continuous fiber to exist concentratedly in the core part of a pellet and dispersing electrically conductive powder, foil or short fiber in a resin surrounding said fiber in a pellet contg. electrically conductive materials incorporated therein. CONSTITUTION:A pellet-shoped electrically conductive molding material has such a structure that electrically conductive fiber 2 running from one end of the pellet to the other end is allowed to exist in the core part of the pellet and covered with a thermoplastic synthetic resin 1 contg. electrically conductive powder, foil and/or short fiber 3 uniformly dispersed therein. Examples of the electrically conductive fibers are metallic fiber and metal-coated fiber of 2-15mm in length. Examples of the electrically conductive powder, foil and short fiber are metal and metal-coated carbon or glass fiber. Pref. the short fiber has a length of 0.1-3mm.
