Patent number: 6894682Abstract: Improves the connection between a touch panel and an external harness. A first electrode cable (11) and a third electrode cable (13) are disposed on a first ITO film (20) on a glass substrate (10) of a touch panel, and a second electrode cable (12) and a fourth electrode cable (14) are disposed on a second ITO film (60) on a flexible resin (50). First to fourth guide conductors (31 to 34) are disposed in parallel on a first insulation layer (30) that is provided near a first side (10a) of the glass substrate. The first to fourth electrode cables are connected to the first to fourth guide conductors, via first to fourth connection conductors (21 to 24). A second insulation layer (40) is laminated on them. On a connection section (6) of an external harness (4), first to fourth external conductors (81 to 84) have their coating removed at the touch panel side, and are superimposed with the plurality of guide conductors of the touch panel so that they cross each other.Type: GrantFiled: February 27, 2003Date of Patent: May 17, 2005Assignee: Fujitsu Component LimitedInventors: Takashi Nakajima, Mitsuaki Nakazawa, Kazuyuki Yoshifusa
