PROBLEM TO BE SOLVED: To obtain a propylene-based resin composition which allows easy production of moldings having excellently balanced rigidity, heat resistance, and particularly impact strength at low temperatures. SOLUTION: This propylene-based resin composition is obtained by mixing a propylene-based polymer having a propylene unit at 100-80 mol.% a constituting unit derived from a comonomer at 0-20 mol.%, an MFR of 0.1-200 g/10 min, an average elution temperature at 75-120 deg.C, and eluted fraction dispersion of 9 or less, with glass fiber and an 'unsaturated carvboxylic acid'-modified polypropylene and, if necessary, an elastomer and/or a Tiegler-based polypropylene, wherein, eluted fraction dispersion,σ=T84.1 -T15.9 (T84.1 is temp at the time when the accumulated amount of eluted fraction reaches 84.1 wt.%, and T15.9 is temp, when the above becomes 15.9 wt.%).
