<P>PROBLEM TO BE SOLVED: To provide a propylene-based resin composition having good melt-processability, such as rigidity, impact resistance, draw down resistance and the like, resulting in enhanced heat stability, and excellent in recyclability; and its molded product. Ž<P>SOLUTION: The composition consists of 0-79 wt.% of crystalline polypropylene having prescribed MFR; 20-99 wt.% of propylene-based polymer comprising p-xylene-insoluble and p-xylene soluble components satisfying prescribed requirements and having prescribed Mw, prescribed amount of component insoluble in hot p-xylene, prescribed strain hardening (λmax) during measurement of elongational viscosity and prescribed MFR; and 1-50 wt.% of thermoplastic resin selected from a hydrogenated styrene-conjugated diene block copolymer having prescribed MFR, an ethylene-α-olefinic copolymer rubber having prescribed Mooney viscosity, and an ethylene polymer resin having prescribed MFR and prescribed density.
