の窓用としても有用である。A conventional infrared absorption filter is a transparent medium which is a solution in which water is used as a solvent and ferrous sulfate as an infrared absorbing agent and sulfuric acid as a reducing agent are added between transparent plates provided facing each other. This is a structure in which the spectral characteristic diagram of FIG. 4) is housed in a sealed state. According to this, a part of the light in the infrared wavelength region that suppresses the growth of the plant is absorbed and cut, and since it is possible to prevent high temperature damage, it is good even under the conditions of strong sunlight in summer, which was conventionally difficult. Harvest is obtained. Further, it is also useful as a window for general construction because it has sufficient transmission of visible light.

That is, since the light-transmitting medium is mainly composed of water, even if a water-resistant adhesive is used for the sealed portion of the transparent plate, it tends to deteriorate with time. Further, if there is a slight gap in the sealed place, the light transmissive medium leaks or evaporates to reduce the amount of liquid, and the function as a filter cannot be achieved.
