Description of the Related Art As a laminated glass for automobiles, there is a laminated glass in which a heat ray reflecting film is interposed between glass plates so as to reduce the heat sensation and cooling load of an occupant. Laminated glass with a general heat ray reflection function has a sandwich structure in which both sides of an Ag film are sandwiched between transparent metal oxides such as ZnO, TiO 2 , ITO or SnO 2 films on the inner surface of the glass plate on the outside of the car. The heat ray reflective film is formed, and the surface on which the heat ray reflective film is formed and the outer surface of the glass plate, which is the inside of the vehicle, are joined via an intermediate film such as polyvinyl vinyl chloride.
