Claim:
A parallel-transmission flat cable that is equipped with a connector unit comprising: a parallel-transmission flat cable member that has pairs of signal transmission paths and ground portions that are arranged alternately so as to enable parallel transmission, and has pairs of signal terminal portions and ground terminal portions exposed at either end of the parallel-transmission flat cable member; and a connector unit forming member that is provided at either end of the parallel-transmission flat cable member and forms a connector unit that has the signal terminal portions and the ground terminal portions of the parallel-transmission flat cable member serving as terminal portions, the connector unit being located at either end of the parallel-transmission flat cable member; and base members are formed integrally with a core part on both sides in said connector unit forming member, and first and second flat cables of said parallel-transmission flat cable member are located between the base members; and guide arms are formed in the base members for guiding connection of said connector unit with a second connector; wherein the guide arms extend from ends of the base members; the parallel-transmission flat cable member has the first flat cable placed onto and bonded to the second flat cable, except at either end, with said terminal portions being formed on an upper surface of either end of the first flat cable and a lower surface of either end of the second flat cable; the connector unit forming member is a plate-like member that is interposed between either end of the first flat cable and the corresponding end of the second flat cable; either end of the first flat cable is fixed onto an upper surface of the corresponding connector unit forming member, while either end of the second flat cable is fixed to a lower surface of the corresponding connector unit forming member; and the connector unit is of a plug type, with the terminal portions of the first flat cable being arranged on the upper surface, and the terminal portions of the second flat cable being arranged on the lower surface.
