ABSTRACT:
A method of forming a pattern in a conductive film of the group consisting of indium oxide film, indium tin oxide film, and aluminum film, covering a surface of a substrate of glass or a plastic material. This is accomplished by contacting a metal electrode with the surface of the substrate, and moving the area where the electrode contacts the conductive film at a speed of 5 to 1000 mm/sec while a voltage of 5 to 60 volts is applied between the electrode and the film.
