Abstract
When a transparent conductive film formed on a glass sheet is heat-treated in the air, its conductivity decreases. Even if the conductivity is increased by a heat treatment in a nitrogen atmosphere or the like beforehand, it decreases considerably by heating in the air during a processing step to obtain a final product. The present invention provides a glass sheet with a transparent conductive film, in which the increasing rate of its sheet resistance is 15% or lower even after heating at 450° C. in the air for three hours.
