摘要：A sodium-containing glass substrate has a modified surface on which anelectroconductive film is to be formed. The modified surface is constituted of a layer ofwhich sodium concentration is lower than the bulk body of the glass substrate,preferably with a sodium content ratio to all the metal elements of not greater than 2atomic percent. The modified surface may contain a reduced amount of sulfur ascompared to the bulk body of the glass substrate.
