  • Patent number: 8791394
    Abstract: The present invention is to provide a heating substrate equipped with a conductive thin film and electrodes. The heating substrate includes a transparent substrate, a plurality of electrodes formed on a first face of the substrate, and a conductive thin film formed on the first face of the substrate and including a plurality of regions electrically connected each other in parallel by the plurality of electrodes. Furthermore, a method of manufacturing a heating substrate equipped with a conductive thin film and electrodes according to an exemplary embodiment of the present invention includes forming the conductive thin film on a substrate, forming main electrodes so as to extend on the substrate while being adjacent to edges of the conductive thin film, and forming branched electrodes that are extended from the conductive thin film across one side of the conductive thin film while coming in contact with the conductive thin film.
