A flexible flat cable has a single conductor or a plurality of conductors, juxtaposed to each other or one another, which are sandwiched between a pair of plastic films with an adhesive to form an integral structure. The plastic films with an adhesive have a modulus of longitudinal elasticity of not less than 300 kg/mm and an elongation of not less than 20%. The plastic films are formed of a polyimide. The adhesive is formed of an epoxy having a glass transition temperature Tg of 80° C. or above, and the 180° peel strength between the adhesive and the single conductor or the plurality of conductors is not less than 0.5 kg/cm.
