Provided is a propylene-based resin composition containing a high proportion of an inorganic filler and excellent in flexibility, mechanical strength, elongation at break, heat resistance, scratch resistance, whitening resistance and flame retardancy. about. The propylene resin composition (X6) of the present invention comprises 0 to 80% by weight of a propylene polymer (A6) having a melting point of 120 to 170 ° C. measured by a differential scanning calorimeter (DSC). 5 to 85% by weight of a propylene-based polymer (B6) having a melting point of less than 120 ° C. or no melting point measured by differential scanning calorimetry (DSC) and a mm fraction of 85% or more, elastomer (C6) 0 to 40% by weight in total and 15 to 80% by weight of inorganic filler (D6) (wherein (A6), (B6), (C6) and (D6) total amount of components is 100% by weight)) (B6) is a propylene / ethylene / α-olefin random copolymer (B6-2) having a molecular weight distribution of 1 to 3 and having 4 to 20 carbon atoms.
