Zusammenfassung:	PURPOSE: A polypropylene-based resin composition is provided to have excellent mechanical properties, light weight, and excellent electromagnetic-wave blocking effect. CONSTITUTION: A polypropylene-based resin composition includes 55-75 wt% of a polypropylene-based resin; 15-25 wt% of a fiber filler coated with metal; 5-10 wt% of a thermoplastic elastomer; 0.1-5 wt% of a nonconductive filler; and 1-5 wt% of a compatibilizing agent including a silane-based function group. The polypropylene-based resin is a propylene homopolymer or a blended resin of a propylene homopolymer and a propylene-ethylene copolymer. The maximum viscosity of a xylene extract from the propylene-ethylene copolymer is 3.0 dl/g or more, and the content of ethylene is 3-15 wt%.
