PURPOSE:To make it possible to obtain easily a stereostructure forming laminated body on the spot by laminating alternatively low heat-shrinkable sheets and highly heat-shrinkable sheets at a specified interval each into five layers through a stripe-like partially adhesive layer and perforating holes feeding hot air from the surface layer to the highly heat-shrinkable sheet of the inner layer. CONSTITUTION:Low heat-shrinkable sheets 1 and highly heat-shrinkable sheets 2 are alternatively laminated each with an adhesive layer 3 at a specified interval intermittently into at least five layers. The adhesive layer 3 is partially adhered into a stripe-like shape at a specified interval. Holes 4 for feeding hot air to the highly heat-shrinkable sheets 2 of the inner layer are formed on the surface. When the hot air is fed from the holes to the inner layer, low heat-shrinkable sheets 1 exhibit larger shrinkages than those of the highly heat- shrinkable sheets 2 to become bulky between the adhesive layers 3 and to form a stereo-structure forming laminated body. Therefore, making it bulky can be performed without using foaming gas and a stable stereo-structure forming laminated body with high strength can be obtd.
