題を有している。As a method of imparting an infrared ray shielding function from sunlight to a transparent glass plate mainly used for windows, a resin film having a metal such as aluminum vapor-deposited is attached to the inside of the glass plate. The method is known. In this method, the resin film is easily peeled off,
It has the drawbacks of being easily scratched, reflecting visible light, darkening the room, lacking in durability, causing light pollution, and difficult to install on a large area of glass. ing.

良好といえない。A solar radiation absorbing glass plate is commercially available as a glass plate having an infrared ray blocking function. However, since this glass plate blocks solar radiation by absorption, the temperature of the glass plate rises in the summer and re-radiation of heat occurs from the glass plate. Therefore, the temperature in the room rises and the effect of energy saving is small. Furthermore, at high temperatures, the risk of glass plate breakage increases due to the increased thermal stress of the glass plate. In addition, since the temperature of the room is absorbed and the heat is radiated to the outdoors in winter, the heat insulation of the glass plate is not good.

がある。。It is well known that metal oxides such as antimony oxide-doped tin oxide and tin oxide-doped indium oxide have conductivity and reflect infrared rays. A glass plate having a thin film of these metal oxides formed on the surface of the glass plate by a sputtering method is commercially available as a high-performance infrared reflecting glass plate which solves the above-mentioned drawbacks of the conventional solar radiation absorbing glass plate. However, in order to mass-produce this high-performance infrared reflective glass plate, a large-sized sputtering device is required, which makes the manufacturing cost high. Further, there is a defect that it is not suitable as a construction method for a large-area glass plate. .

幅広い用途がある。The laminated transparent substrate thus obtained has a high infrared shielding property due to the infrared reflectivity of the sputtered thin film of the conductive metal oxide or the thin film coated with the conductive metal oxide fine particles, and is also highly transparent. Therefore, it has a wide range of applications such as window glass for automobiles, window glass for buildings, and glass plates for showcases.
