Polypropylene resin composition, sheet molded body, and container

A polypropylene-based resin composition comprising

• a polypropylene-based resin (A) including a continuous phase consisting of a propylene polymer (a1) and a rubber phase consisting of a copolymer (a2) of ethylene and α-olefin having 3 to 10 carbon atoms, and
• an ethylene/α-olefin polymer (B) which is a polymer of ethylene and α-olefin having 2 to 10 carbon atoms, and
• an inorganic filler (C) as an optional component,
• wherein the MFR of the polypropylene-based resin composition at a temperature of 230° C. and a load of 2.16 kg is 0.1 to 3.0 g/10 minutes,
• the total weight of the (A), (B) and (C) is 70% by weight or more with respect to the total weight of the polypropylene-based resin composition,
• the total weight of the (A) and (B) is 50% by weight or more with respect to the total weight of the polypropylene-based resin composition,
• the content of the (A) is 99 parts by weight or less, the content of the (B) is 1 part by weight or more, and the content of the (C) is 0 to 60 parts by weight with respect to the total 100 parts by weight of the (A), (B),
• the content of ethylene-derived units in the propylene polymer (a1) is 0.5% by weight or less with respect to the total weight of the propylene polymer (a1),
• the content of the copolymer (a2) is 27 to 45% by weight with respect to the total weight of the polypropylene-based resin (A),
• the content of ethylene-derived units in the copolymer (a2) is 25 to 85% by weight with respect to the total weight of the copolymer (a2),
• the xylene-soluble portion of the polypropylene-based resin (A) has an intrinsic viscosity in tetrahydronaphthalene at 135° C. of 2.5 to 5.5 dl/g.
