METHOD FOR MANUFACTURING TOUCH PANEL

PROBLEM TO BE SOLVED: To provide a method for manufacturing a touch panel by which registration accuracy between sensor electrodes formed by disposing two layers on a transparent substrate can be improved without increasing the number of processes, and thereby generation of uneven density in the sensor electrodes due to poor registration accuracy can be suppressed.SOLUTION: A method for manufacturing a touch panel 10 is provided, the touch panel having two layers of a first sensor electrode 3a and a second sensor electrode 3b as a sensor electrode 3 on one surface of a transparent substrate 1. The method employs 'a draw-out primer system intaglio printing process' as a printing system of forming the sensor electrodes, in which printing is performed via a primer fluid layer 2F in flow condition that finally turns into a primer layer 2, for forming the sensor electrodes by continuously printing two layers on the same apparatus. In the above printing process, a second primer layer of a first primer layer 2a and a second primer layer 2b which are essential in the printing method is formed to be also an interlayer insulating layer between the first sensor electrode and the second sensor electrode.
