PURPOSE: To provide a laminated body for sandwich glass which has a heat insulating function and good appearance by forming a thin metallic film layer having a function such as selective light transmittance or the like on one surface of a polyethylene terephthalate film and adhering a reinforcing film on the other surface.
CONSTITUTION: A thin metallic film layer 2 consisting of a thin metallic film having selective light transmittance (e.g., thin aluminum film) or a thin transparent conductive film (e.g.; a film consisting of indium oxide and tin oxide), etc. is formed on one surface of a base plate 1 consisting of a polyethylene terephthalate film having 40μm thickness. A reinforcing film 4 consisting of a polyethylene terephthalate film having ≥45μm thickness is adhered via an adhesive layer 3 on the other surface of the plate 1 to manufacture a laminated body 5 for intended sandwich glass. Polyvinyl butyral sheets 6 are laminated on both surfaces of such body 5 and the resultant intermediate body is sandwiched by glass plates 7 and are subjected to thermocompression bonding, by which the sandwich glass is obtd.
