Abstract: A method for producing a skin-covered foamed molded article including blow-molding a parison in a mold cavity to form a skin consisting of a hollow molded body, in which the parison is in a softened state by extruding a molten thermoplastic resin, filling expanded beads in the hollow molded body, and heating and fusion bonding the beads by supplying steam via a steam supply pipe inserted into the hollow molded body. The parison is in contact with a protruding portion, formed by protrusion from an inner surface of the mold cavity to an inside of the cavity, forming a recessed portion having a shape corresponding to the protruding portion in the inward direction of the hollow molded body. A steam hole is formed in the recessed portion, a steam supply pipe is inserted into the body, and the expanded beads are heated and fusion bonded by supplying steam.
