PROBLEM TO BE SOLVED: To provide a flexible flat cable in which there is no possibility that whisker of Sn is formed and that an adhesive is deteriorated, and in which material cost does not increase greatly compared with that of a TPA wire. SOLUTION: This is the flexible flat cable in which a plurality of numbers of conductors are arranged in parallel with a prescribed spacing between two sheets of insulating tapes. At both ends of the flexible flat cable, the conductors have exposed parts exposed from one insulating tape formed over a prescribed length, the conductors are formed by installing Sn layers on surfaces of conductive base bodies, and in the conductors of the exposed parts, Ni layers are installed on the Sn layers, and furthermore, Au layers are installed on the Ni layers.
