A touch panel manufacturing method, comprising:
- sequentially laminating a transparent conductive film layer and a metal layer on an insulative transparent substrate, and thereafter, forming the transparent conductive film layer and the metal layer into a predetermined electrode pattern, using a same resist pattern;
- forming a protective film that covers the transparent conductive film layer and the metal layer, and providing an opening at a predetermined position in the protective film so that the opening passes through the protective film;
- and
- removing the metal layer by etching with use of the protective film having the opening, so as to expose the transparent conductive film layer, thereby forming at least one of a touch electrode and a connection terminal that outputs a potential of the touch electrode to outside of the touch panel;
- sequentially laminating the transparent conductive film layer of a first layer and the metal layer of the first layer on the transparent substrate, and thereafter, forming the transparent conductive film of the first layer and the metal layer of the first layer into a predetermined electrode pattern, using a same resist pattern;
- forming the protective film of the first layer that covers the transparent conductive film layer of the first layer and the metal layer of the first layer;
- sequentially laminating a transparent conductive film layer of a second layer and a metal layer of the second layer on the protective film of the first layer, and thereafter, forming the transparent conductive film layer of the second layer and the metal layer of the second layer into a predetermined electrode pattern, using a same resist pattern;
- forming a protective film of the second layer that covers the transparent conductive film layer of the second layer and the metal layer of the second layer;
- providing the opening of the first layer at the predetermined position in the protective film of the first layer and providing an opening of the second layer at a predetermined position in the protective film of the second layer so that the opening of the first layer passes through the protective film of the first layer and the opening of the second layer passes through the protective film of the second layer;
- and
- removing the metal layer of the first layer and the metal film of the second layer by etching with use of the protective film of the first layer having the opening of the first layer and the protective film of the second layer having the opening of the second layer, so as to expose the transparent conductive film layer of the first layer and the transparent conductive film layer of the second layer, thereby forming at least one of the touch electrode and the connection terminal.
