<p>The invention relates to a glass pane including (a) a glass substrate having first and second major surfaces opposed to each other, (b) a functional film formed on the first major surface of the glass substrate, and (c) a conductive wire formed on the functional film. This glass pane is produced by a process having the sequential steps of (a) applying a coating liquid to the first major surface of the glass substrate, thereby forming thereon a first precursory film; (b) subjecting the coated glass substrate to a first baking at a first temperature of 550-620 DEG C, thereby turning the first precursory film into a second precursory film; (c) printing a metal-containing paste on a part of the second precursory film, thereby forming thereon a precursory conductive wire; and (d) subjecting the coated glass substrate to a second baking at a second temperature of 600-670 DEG C which is higher than the first temperature, thereby turning the second precursory film and the precursory conductive wire into the functional film and the conductive wire, respectively. The second major surface of the glass substrate has a depression at a position corresponding to the conductive wire. This depression is made to have a depth not greater than 1 mu m by the process. Therefore, the glass pane can be suitably used as an automotive rear window pane. <IMAGE></p> |
