PROBLEM TO BE SOLVED: To obtain a propylene based resin composition which excels in the balance between normal temperature/low temperature impact resistance, low temperature brittle temperature, and tensile elongation at break and heat distortion resistance, and rigidity. SOLUTION: This propylene based resin composition comprises (A) a polypropylene based resin, (B) a rubbery polymer, and (C) a not less than 90% hydrogenated block copolymer and have a dispersion morphology in which component (A) forms a continuous phase in which component (B) is present as the dispersion phase (first dispersion phase), and furthermore, a dispersion phase in which component (C) is dispersed at the interface of the first dispersion phase and/or in the first dispersion phase [second (a) dispersion phase] and the continuous phase [second (b) dispersion phase], respectively, at a ratio of formation of the second (a) dispersion phase to the second (b) dispersion phase by component (C) of 30/70 to 85/15. |
