摘要:
A skin-covered foamed molded article having excellent lightweight property, bending rigidity, and favorable dimensional stability, which includes: a skin material composed of a hollow molded body produced by blow-molding an extruded parison; and an expanded bead molded article located inside the skin material, wherein the skin material has an average wall thickness of from 1.0 mm to 5.0 mm, the skin material includes a glass fiber-reinforced polypropylene-based resin containing glass fiber in a range of from 5 mass % to 30 mass %, the glass fiber has a weight-average fiber length of from 0.4 mm to 1.5 mm, the expanded bead molded article includes a polypropylene-based resin, the peeling strength between the skin material and the expanded bead molded article is 0.1 MPa or higher, and the longitudinal linear expansion coefficient of the skin-covered foamed molded article (100) at from 23° C. to 80° C. is 7×10−5/° C. or lower.
