Abstract
In FFC1 integrated by sandwiching flat type conductors between plastic films with adhesives, wherein the conductors are formed of pure copper or a copper alloy having a wiredrawing draught of at least 95% and an elongation of at least 5%, and the plastic films with adhesives are formed of one having a modulus of longitudinal elasticity of at least 280 kg/mm and an elongation of at least 80%, and the 180° peel strength between the adhesives and the conductors is made to be at least 0.8 kg/cm. As a result, even if the number of conductors is increased than the conventional FFC, bending-resistant characteristic equal to or higher than the conventional FFC can be exhibited.
