Provided is a polypropylene-based resin composition that can produce a lightweight foam sheet and a thermoformed article, which have uniform, fine foamed cells and have excellent appearance, thermoformability, impact resistance, rigidity, thermal resistance, thermal insulating properties, oil resistance, etc. The polypropylene-based resin composition and the like are characterized by including 5-99 wt% of a polypropylene resin (X) that has properties (X-i) to (X-iv) and a long-chain branched structure, as well as 1-95 wt% of a propylene-based block copolymer (Y) that has properties (Y-i) to (Y-v) and is formed from a propylene (co)polymer (Y-1) and a propylene-ethylene copolymer (Y-2), which are produced by sequential polymerization. |
