PROBLEM TO BE SOLVED: To reduce crosstalk noises between flat cables and in a flat cable. SOLUTION: FFC 10a and 10b have a ground line 12 greater in width than a signal line 11. Because of this, a voltage induced on the ground line 12 by a signal on the signal line 11 becomes lower, compared to a case where the ground line 12 is identical in width with a signal line 11. Even if the FFC 10b is set superposed on the FFC 10a, a plurality of projections 14 of the FFC 10a serve as spacers to keep a gap between flat cables 200μm or more. As a result, interference between one flat cable and another flat cable in wiring becomes smaller, compared to a case of the absence of the projections 14. COPYRIGHT: (C)2009,JPO&INPIT
