As a result, the base material 3 is installed with a predetermined gap 51 (approximately 15 mm) between the skin 7 and the skin 7. That is, since the molding surface 25 of the mold 19 is formed in a recess, a predetermined gap 51 is formed when the base material 3 is installed. The base material 3 is made of a polypropylene solid resin containing a filler, and has a plurality of ventilation holes 9 and material supply holes 11 formed therein. Next, the upper molding part 15 is lowered, and the base material 3 is fixed in the upper molding part 15, and the mold is clamped with the lower molding part 13. Subsequently, foamable resin beads M are supplied to the gap 5 from a material supply device (not shown) through the pipe line 53 and the through hole 11 of the base material 3.
Supply to 1. The foamable resin beads M are made of polypropylene, have an average particle diameter of 7 mm, and are formed to have a soft feel by increasing the expansion ratio from 11 times to 45 times.

The steam is sent into the gap 51 through the through hole 36 of the molding part 35 and the through hole 9 of the base material 3. As a result, the foamable resin beads M are heated and foamed to form the foam layer 5. This foam layer 5 welds the skin 7 and the base material 3 without any gaps. Thereafter, the product is cooled, and the upper molding section 15 is raised to take out the product, thereby completing the series of steps.
