PROBLEM TO BE SOLVED: To manufacture a thermoforming laminated sheet capable of preventing the occurrence of resin dusts effectively as a result of employing means not making the transparency worse with respect to the film side and means not making the heat resistivity low with respect to the foaming sheet side. SOLUTION: The foam sheet portion 3 is 0.13-0.5g/cm<3> in its apparent density and 0.3-2.0mm in thickness. The number of bubbles is 100-300 pieces/4mm<2> in the side surface of the foam sheet portion 3 of a laminated sheet. Also, the foundation resin forming a film 2 is a mixture of stylene-butadiene block copolymer of a mixture of the copolymer and a stylene homopolymer, and the content of a butadiene component in the whole part of substrate material resin is 5-25wt.% and the content of a stylene component of the stylene-butadiene block copolymer is 60-95wt.%. Also, the thickness of the film 2 is 5-50μm. |
