Claim Text:
1. A manufacturing method of a touch panel comprising the steps of: providing a substrate; forming a first conductive film on the substrate; forming a first mask on the first conductive film; etching the first conductive film to form a plurality of electrode portions and a plurality of lower intersect portions of the touch panel; removing the first mask; forming an insulating film made of a negative resist on the first conductive film; forming a contact hole above one of the plurality of electrode portions by removing the insulating film; forming a second conductive film on the insulating film; forming a second mask on the second conductive film; etching the second conductive film to form an upper intersect portion connected between two adjacent electrode portions of the plurality of electrode portions via the contact hole and intersecting with one of the plurality of lower intersect portions; removing the second mask; and forming a protective film from a negative resist on the second conductive film over the insulating film.
