    摘要: A method for producing a skin-covered foamed molded article, including blow-molding a parison of a polypropylene-based resin composition into a skin defining a hollow space, placing thermoplastic resin expanded beads in the hollow space, and heating the expanded beads placed in the hollow space to fuse-bond the expanded beads together, wherein the polypropylene-based resin composition has a tensile elongation at break at 80° C. of 300 to 1,000% and a half-crystallization time at 130° C. of 5 to 50 seconds.
