１〜５：１であるのが好ましい。 The glass fiber reinforced thermoplastic resin film used in this invention is polystyrene, polyethylene,
The film is reinforced by impregnating glass fiber with a thermoplastic resin such as polyvinyl chloride, and the thermoplastic resin is preferably the same resin as the resin constituting the foamed sheet. The glass fibers are preferably non-woven fabrics bound by a granular or thread-like binder that softens at a temperature of 140° C. or lower so that the foamed sheet can be shaped without heat loss during heat shaping. As the binder, for example,
ABS resin, acrylic resin, cellulose, acetate, propionate polybutene, ethylene-
Examples include vinyl acetate copolymer, polyethylene, polypropylene, polystyrene, polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, SBR, NBR, polyvinyl acetate, and modified polyamide. In addition, the ratio of resin to glass fiber constituting the resin film is such that as the ratio of resin increases, the weight increases and the reinforcing function of glass fiber is diminished, and as the ratio of resin decreases, it becomes difficult to fuse with the foam sheet. :
Preferably, the ratio is 1 to 5:1.

発泡シートの重量比は１：２〜２：１であるのが
好ましい。 The weight ratio of the foam sheet to the resin film is not particularly limited, but if the ratio of the resin film is small, the strength will be low, the heat resistance will be low, and it will be easily deformed by heat. The weight ratio of the resin film on both sides and the foam sheet is preferably 1:2 to 2:1, since this may cause the foam sheet to become heat-weakened or buckled during shaping.
