Zusammenfassung:PROBLEM TO BE SOLVED: To provide a propylene-based resin composition having excellent stiffness and heat resistance, and a molded article of the composition. SOLUTION: The propylene-based resin composition includes 10-89 mass% of a propylene-based polymer (A) except a modified propylene-based polymer (C) defined below, 10-89 mass% of a polylactic acid resin (B), and 1-80 mass% of the modified propylene-based polymer (C) produced by grafting α,β-unsaturated glycidyl ester, wherein a content of a structure unit derived from the α,β-unsaturated glycidyl ester is 0.1-1.0 mass%, when the total mass of the modified propylene polymer (C) is assumed to be 100 mass%.
