The present invention pertains to a skin-covered foamed molded article of expanded propylene resin beads having excellent lightness in weight, mechanical properties and appearance. n The present invention provides a skin-covered foamed molded article of propylene resin expanded beads, with the skin covering substantially the entire surface of the molded article of the expanded beads. The skin, within which the molded article of expanded propylene resin beads is placed, is a propylene resin hollow molded body obtained by blow molding. A base resin of which the skin is formed comprises a propylene resin having a partial heat of fusion in a temperature range between 80 and 140° C. of at least 15 J/g and a ratio of the partial heat of fusion to a total heat of fusion (partial heat of fusion/total heat of fusion) of at least 0.2 as measured by heat flux differential scanning calorimetry. The skin has a thickness in the range of 0.3 to 3.5 mm, and the molded article of expanded propylene resin beads has an apparent density in the range of 0.015 to 0.15 g/cm 3 . The skin is fuse-bonded to the molded article of expanded beads, and the expanded beads from which the molded article is formed are fuse-bonded to each other. |
