Abstract

See full text

A window pane for an automobile includes a single sheet of glass plate and an infrared cutoff film formed on the single sheet of glass plate. A film thickness of the infrared cutoff film on an upper portion of the window pane is greater than the film thickness on a lower portion of the window pane when the window pane is installed in the automobile. A variation from a minimum value in the film thickness on the lower portion to a maximum value in the film thickness on the upper portion is at least 1000 nm per 600 mm in a vertical direction of the window pane when installed in the automobile. The infrared cutoff film is formed on a surface of the single sheet of glass plate by using a flow coating method.
