Abstract
A conductive glass with a coat constituted mainly of a potassium-contained stannic oxide applied on a glass substrate, wherein a film thickness of the coat constituted mainly of the stannic oxide comes within the range of 1 to 100 nm, a potassium concentration is 0.1 to 10.0 wt %, and a surface compression stress of the conductive glass is 30 to 100 kg/mm.sup.2. After the stannic oxide coat is formed on the glass substrate, it is brought into contact with a melted potassium nitrate to contain potassium in the glass substrate and the coat.
