The lamination made of four layers of polystyrene foam can be fused and strongly integrated with the molding plate simultaneously with molding of the molding plate with the styrene-based resin expanded particles by alternately changing the directionality formed by extrusion stretching in the vertical and horizontal directions. Have. With the four-layer laminate, the molded plate is reinforced by the expanded styrene resin particles to improve the strength. Because of the high foaming, the weight can be reduced and the cushioning can be maintained. Warpage can be prevented and corrected by the laminate having crossed directions. The soundproof, moistureproof and heat insulating effects can be improved. Resource saving of natural wood can be realized (40% or more). Cutting is easy. Recycling is easy because of the lamination of styrene resins.
