Abstract:
A glass substrate having a transparent conductive film, which is used to laminate a film for a functional element thereon to form a laminate structure,said glass substrate comprising 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 Ã¥ or larger and is made of a crystalline metal oxide, a continuous alkali barrier film made of SiO2 and having such a small thickness as to reflect the surface roughness of the undercoat, and a transparent conductive film made of SnO2 doped with one or more impurities and having a thickness of 5,000 Ã¥ or larger, said transparent conductive film having an adhesion strength of 37 mN or higher as measured in accordance with â€œAdhesion Test for Thin Film Deposited on Glass Substrate â€  as provided for in JIS R3255-1997.
