Abstract
A glass substrate having a transparent conductive film of SnO is disclosed, in which the transparent conductive film is prevented from developing hair cracks even when it has a thickness of 5,000 Å or larger. The glass substrate comprises an alkali-containing base glass plate having a smooth surface and, formed thereon in this order, an undercoat for imparting roughness which has a thickness of 150 Å or larger and is made of a crystalline metal oxide, a continuous alkali barrier film made of SiO and having such a small thickness as to reflect the surface roughness of the undercoat, and a transparent conductive film made of SnO doped with one or more appropriate impurities and having a thickness of 5,000 Å or larger. The transparent conductive film has an adhesion strength of 37 mN or higher as measured in accordance with “Adhesion Test for Thin Film Deposited on Glass Substrate ” as provided for in JIS R3255-1997.
