| description | PROBLEM TO BE SOLVED: To easily suppress drawdown quantity by setting the shrinkage factors in the extrusion direction and widthwise direction of a foamed laminated sheet, wherein non-foamed layers of a thermoplastic resin are laminated on both surfaces of a foamed sheet containing a heat-resistant resin as a base resin to specific values. SOLUTION: Non-foamed layers 14, 16 comprising a thermoplastic resin are laminated to both surfaces of a foamed sheet 12 containing a heat-resistant resin as a base resin. The shrinkage factors of this foamed laminated sheet 10 and the foamed sheet 12 in the extrusion direction and widthwise direction thereof at molding heating temp. T1 ( deg.C) are set to 0.5% or more and 8% or less. The molding heating temp. T1 ( deg.C) is set to T ( deg.C) -30 deg.C |
