PROBLEM TO BE SOLVED: To provide a propylene resin composition having an excellent impact resistance, especially low temperature impact resistance, flexibility, transparency and heat resistance. SOLUTION: This propylene resin composition comprises polypropylene component and a propylene ethylene copolymer component and (1) the composition comprises 90-50 mol% of propylene monomer unit and 10-50 mol% of ethylene monomer unit, (2) this composition comprises 20-50 wt.% of a component (A) eluting at <=20 deg.C in a temperature programmed elution fractionation using O-dichlorobenzene as a solvent, 10-70 wt.% of a component (B) eluting at 20 to 85 deg.C, 3-10 wt.% of a component (C) eluting at 85 to 100 deg.C and 10-50 wt.% of a component (D) eluting at >=100 deg.C, the sum of the components (A) to (D) is 100 wt.% and (3) the component (C) comprises 80 to 20 mol.% of the propylene monomer unit and 20 to 80 mol.% of the ethylene monomer unit.
