HIGH FREQUENCY CORRESPONDENCE FLEXIBLE FLAT CABLE

PROBLEM TO BE SOLVED: To solve the problems that area saving can not be achieved due to the lowness of the degree of freedom of a mounting position of a connector with a round cable connected because the round cable is lack of flexibility even though the round cable is used as a transmission line in a wiring material used in a high frequency area corresponding to high-speed transmission, and that the simplification of a processing process and the reduction of the number of components are difficult to achieve because noise countermeasure and impedance matching have to be taken into consideration.SOLUTION: A tongue piece-shaped connector fitting piece in which a signal line is exposed on a surface side and a ground layer made of a conductive material is exposed over an entire width of a rear side in a width direction, respectively, and a notch for coming-off prevention is formed at both side edges is formed at an end of a flat band-like flexible flat cable body with a signal line embedded inside in a longitudinal direction.
