Patent ID: 6847355

Claim:
A touch panel manufacturing method comprising: arranging a flexible touch side panel and a base side panel to face each other via an insulating spacer in an analog resistance film form, a transparent electrode and a pair of parallel lead electrodes being provided onto one face of a transparent insulating base member of each of the panels in a state with the transparent electrode set inside and the lead electrodes of one of the panels disposed in a rectangular arrangement along with the lead electrodes of the counterpart panel, either one of the touch side panel and the base side panel having the transparent electrode set to an entire face of the transparent insulating base member thereof, the other having the transparent electrode set to part of the transparent insulating base member thereof and including, at an insulating part other than the transparent electrode, independent connection electrodes; and connecting, via a conductive adhesive, the connection electrodes set to one of the panels to the lead electrodes set to the opposing panel, the conductive adhesive being made up of main conductive fillers of flakes or spheres or short fibers, and a spherical auxiliary conductive filler having an insulating core material coated with a conductive layer and having a larger particle size by 10-100 μm than a minimum distance of contact faces of the lead electrode of one of the panels and the connection electrode of the other of the panels connected by the conductive adhesive, both of the main conductive fillers and the auxiliary conductive filler dispersed in a binder of the conductive adhesive, whereby always keeping the auxiliary conductive filler in touch with the lead electrode of the one of the panels and the connection electrode of the other panels.
