とから製造コストが高いという欠点がある。However, in the case of a glass provided with an organic resin film, if the ultraviolet ray blocking function of the organic resin film is deteriorated by ultraviolet rays or the durability of the organic resin film is not good, another film or glass is used. However, there are drawbacks in that they have to be laminated, the structure must be thick, and the manufacturing cost is high. In addition, glass having a changed glass composition needs to have a constant valence of an element that absorbs ultraviolet rays, and it is difficult to control this valence, and in addition, since the glass composition itself is changed, it is particularly plate glass. In the production of, since it takes time to stabilize the molten composition, there is a problem in that a large amount of glass is wasted, resulting in an increase in cost. Further, in the case of a glass to which a multilayer thin film is attached, this film formation is generally performed by a physical film forming method such as a sputtering method, so that the facility cost is high and the number of man-hours for the multilayer film formation is large, so that the manufacturing cost is high. There is a drawback that.
