PURPOSE: A propylene-based resin composition is provided to ensure excellent processability, impact resistance, elastic modulus, and flexural strength, and to prepare parts for automobile such as a bumper cover, glove box, and pillar. CONSTITUTION: A propylene-based resin composition comprises a propylene-based polymer and an olefin-based copolymer. The olefine-based copolymer is prepared using a catalyst composition. The catalyst composition comprises (a) a metallocene catalyst including two kinds of metallocene catalysts with different reactivity to a co-monomer and (b) a co-catalyst. The propylene-based polymer comprises one kind or more selected from the group consisting of propylene homopolymer, propylene/ethylene copolymer and their mixture.
