Zusammenfassung:PURPOSE:To obtain the subject low-cost paste giving a transparent conductive film having decreased electrical resistance and improved film strength by adding an oxidizing agent as an active component to a paste containing a specific metal compound, an organic solvent and an organic binder. CONSTITUTION:The objective paste is produced by adding an oxidizing agent (preferably a peroxide) as an active component to a paste containing (A) a metal compound giving a transparent electrically conductive metal oxide by baking, e.g. an indium compound and a tin compound, a tin compound and an antimony compound, etc., (B) an organic solvent and (C) an organic binder composed of a cellulose derivative (preferably nitrocellulose, etc.). A transparent conductive film can be formed by printing a pattern on a substrate with the paste, drying the printed pattern, baking in an oxidizing atmosphere, exchanging to a neutral atmosphere and continuing the baking of the product.
