Abstract:
A glass sheet with a transparent conductive film, comprising:a glass sheet; and a transparent conductive film with a thickness of at least 400 nm to 1200 nm formed on the glass sheet, said transparent conductive film including a tin oxide as a main component, wherein the transparent conductive film is formed on the glass sheet or a glass ribbon during a manufacturing process of the glass sheet at a temperature of 600Â° C. or more, and an increase in sheet resistance of the transparent conductive film due to a heat treatment at 450Â° C. in the air for three hours is 15% or lower when the sheet resistance before the heat treatment is taken as a reference; wherein between the transparent conductive film and the glass sheet, a first intermediate film with a thickness of 5 nm to 50 nm and a second intermediate film with a thickness of 5 nm to 50 nm are formed sequentially from a side of the glass sheet; and said first intermediate film includes tin oxide as a main component and said second intermediate film includes a main component selected from the group of silicon oxide and aluminum oxide.
