In FIG. 2, a substrate 4 made of PET (polyester)
Al deposited film 5 by depositing aluminum on
Is formed on the Al-deposited film 5.
An interior material 7 made of (polyethylene) is adhered by a PE film 6. Further, a PE film 8 is adhered on the interior material 7 made of foamed PE. The PE film 6 is applied on the Al-deposited film 5 by extruding molten PE from the nozzle onto the Al-deposited film 5 and stretching it thinly with a roll.
The interior material 7 made of foamed PE and the outermost PE film 8 are laminated by overlapping and heating under pressure. Then, the laminate of the interior material 7 and the PE film 8 is superimposed on the base material 4 with the interior material 7 and the PE film 6 superimposed on each other. The material 7 is joined. The PE film 6 is composed of the Al vapor-deposited film 5 and the foamed PE.
It functions as an adhesive for firmly joining the interior material 7 made of

For example, the thickness of the PET substrate 4 is 10
