PROBLEM TO BE SOLVED: To obtain a resin composition capable of molding an electromagnetic wave shielding article such as a housing of electronic equipment having excellent tensile strength, compressive strength, impact strength, heat, cold, abrasion and creep resistances, etc., and further excellent electromagnetic wave shielding properties, nonhalogen flame retardance, appearance, etc., and further having good fluidity during molding processing and to provide the electromagnetic wave shielding article prepared by using the resin composition. SOLUTION: This thermoplastic resin composition for shielding electromagnetic waves is characterized as comprising (A) a master pellet prepared by coating, forming and integrating the surface of bundled metal filaments with a synthetic resin layer and cutting the integrated material into a pellet form and (B) a resin pellet obtained by adding (c) an organophosphorus compound to a resin component comprising (a) a polycarbonate resin and (b) a rubber- modified polystyrene resin, the mixing ratio (wt.%) of the components (a) to (b) in the resin component is (40-95):(60-5) and the compounding ratio of the component (c) is 1-40 pts.wt. based on 100 pts.wt. of the resin component.
