Flexible Flat Cable

A flexible flat cable comprising:

• a first sheet-like insulator layer;
• a second sheet-like insulator layer disposed in opposition to the first insulator layer;
• a plurality of linear conductors disposed in parallel with each other between the first insulator layer and the second insulator layer;
• a first adjustment material layer disposed on the side of the first insulator layer opposite the conductors and spaced from an end of the flexible flat cable with a predetermined distance;
• a reinforcement plate provided on the side of the first insulator layer opposite the conductors and between the end of the flexible flat cable and the first adjustment material layer;
• a shield member disposed so as to cover the side of the reinforcement plate opposite the first insulator layer and the side of the first adjustment material layer opposite the first insulator layer;
• a first shield layer disposed from the side of the shield member opposite the reinforcement plate to the side of the first adjustment material layer opposite the first insulator layer, with exposing a portion of the side of the shield member opposite the reinforcement plate;
• wherein the second insulator layer is arranged to expose the conductors at the end of the flexible flat cable;
• the exposed conductors and the exposed shield member come into contact with signal terminals and a ground terminal of a connector;
• and
• the shield member includes an impedance adjusting means.
