Abstract:
The objective of the present invention is to achieve a manufacturing method that, in a capacitive touch panel, prevents the occurrence of residue in an electrode film caused by an etching defect for a touch panel in which electrode patterns are difficult to recognize. The manufacturing method for the touch panel includes: an electrode formation step for forming, upon an insulating substrate (10), first electrodes (11) and second electrodes (12) that extend in mutually intersecting directions; an insulating film formation step for forming insulating films (16) which cover portions of the insulating substrate (10), the first electrodes (11), and the second electrodes (12); and a bridge formation step for forming bridges (17) that connect neighboring second electrodes (12) together over the insulating films (16). In addition, before the bridge formation step, a surface treatment step for etching the surface of the first electrodes (11) and the second electrodes (12) is performed one or more times.
