PURPOSE: To cut off infrared rays when the sheet face side is irradiated with infrared rays and transmit infrared rays when the base material film face side is irradiated with infrared rays by a structure wherein the laminate concerned is produced by laminating a sheet having air depressions and a metal deposited film together.
CONSTITUTION: A laminated film 1 is produced by laminating a plastic film 13, which has the cut-off function of the light rays in specified wave length range such as near ultraviolet rays or the like, through a metal deposited layer 12 to a base material film 11, onto which the metal deposited layer 12 is made. Further, a plastic sheet 2 is made of a synthetic resin sheet such as polyethylene sheet or the like having a large number of enclosed swollen-out parts 21, in the interior of each of which air is sealed. Furthermore, a laminated film 1 is integrally laminated under the condition that the base material film 11 face side is made to be a lamination plane to the tip side of the enclosed swollen-out parts 21 of the plastic sheet 2.
