摘要：
Provided is a polypropylene-based resin composition which gives uniform and fine cells and from which a foamed sheet and thermoform excellent in appearance, thermoformability, impact resistance, lightness, stiffness, heat resistance, heat insulating properties, oil resistance and the like can be produced. A polypropylene-based resin composition comprising (X) 5 to 99% by weight of a polypropylene resin having a structure with long chain branches, and (Y) 1 to 95% by weight of a propylene-based block copolymer produced by sequential polymerization, which block copolymer comprises (Y-1) a propylene (co)polymer and (Y-2) a propylene-ethylene copolymer, said resin (X) having properties (X-i) to (X-iv) and said block copolymer (Y) having properties (Y-i) to (Y-v), and the like.
