摘要： PROBLEM TO BE SOLVED: To provide a propylene-based resin composition excellent in molded appearance, rigidity and impact resistance, and injection moldability, and a molded body. SOLUTION: The resin composition includes a propylene-based block copolymer satisfying [1]-[8], an elastomer, a filler, and a luminous material: [1] having a melt flow rate in a predetermined condition of 5 g/10min to 150 g/10min; [2] composed of a predetermined amount of n-decane-soluble portion (Dsol) and a predetermined amount of n-decane-insoluble portion (Dinsol); [3] having molecular weight distribution of Dsol of 7.0 to 20; [4] having an ethylene content of Dsol of 25 to 45 mol%; [5] having intrinsic viscosity of Dsol of 1.8 to 4.0 dL/g; [6] having molecular weight distribution of Dinsol of 7.0 to 20, and Mz/Mw thereof of 6.0 to 20; [7] having a pentad fraction of Dinsol of 95% or more; and [8] having a predetermined value of a copolymerization index of propylene and ethylene in Dsol.
