Provided is a signal transmission flat cable that is capable of suppressing a decrease in signal transmission characteristics in a high-frequency frequency band. An upper electric insulation thin film layer 4 and a lower electric insulation thin film layer 5 are provided, whereby signal conductors 1, 2 and an electric insulation base body 3 are covered from the top and the bottom in the cable thickness direction. A protective insulation layer 8 comprises a metal layer 6 and an electric insulation plastic layer 7, and surrounds the outer periphery of the upper and lower electric insulation thin film layers in such a manner as to position the metal layer on the inside, and the electric insulation plastic layer on the outside. Grounding of the cable is achieved through the metal layer 6 of the protective insulation layer 8. |
