Abstract
A method for producing a skin-covered polyolefin-based resin foamed molded article, including blow-molding a polyolefin parison into a skin defining a hollow space; and placing multi-layered polyolefin expanded beads in the hollow space; and heating the expanded beads placed in the hollow space to fuse-bond the expanded beads together and to fuse-bond the expanded beads to the skin, wherein the expanded beads have specific apparent density, specific average diameter, specific endothermic peaks in their DSC curve and specific melting point characteristics.
