PROBLEM TO BE SOLVED: To reduce cross talks between plural signal paths passing through a jack by providing plural spring jack wires folded at the lowest folding radius by a dielectric mandrel in a jack wire terminal area of a front end of a wire board having a conductive path, and connecting these spring jack wires to a communicating plug. SOLUTION: A printed wire board 12 having a conductive path formed of layers 14, 16 is extended between a jack wire terminal area 18 of a first end and a wire-connecting terminal area 22 of a second end. The predetermined number of spring jack wires 23a-23h are extended backward from a front surface of the wire board 12 at an acute angle with respect to a surface of the wire board 12, while passing through the jack wire terminal area 18, and connected to a plug for communication. At this stage, the jack wires 23a-23h are folded by a dielectric mandrel arranged in the jack wire area 18, and wound around a jack wire block 26 imparting a predetermined bending radius. |
