Zusammenfassung:PROBLEM TO BE SOLVED: To provide a capacitive touch panel having an inconspicuous electrode pattern of transparent electrodes for touch position detection, and a production method of the touch panel.SOLUTION: A touch panel 10 comprises: a transparent adhesive sheet 13; a first electrode layer 1; a second electrode layer 2; a transparent dielectric layer 5 positioned opposite the adhesive sheet 13 with the second electrode layer 2 interposed therebetween: and a conductive layer 3. The first electrode layer 1, the second electrode layer 2 and the conductive layer 3 are formed to be transparent by using a conductive material containing -conjugated conductive polymers. The first electrode layer 1 includes a plurality of first electrodes extending in Y-axis direction and parallel to each other. The second electrode layer 2 includes a plurality of second electrodes extending in X-axis direction and parallel to each other. In plan view, the conductive layer 3 is formed in a lattice shape that fills gaps formed between the adjacent ones of the plurality of first electrodes and gaps formed between the adjacent ones of the plurality of second electrodes.
