PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing apparatus of a cable for differential signal transmission which are capable of reducing skew between a pair of signal line conductors.SOLUTION: A manufacturing apparatus 100 comprises: an extruder 3 which coats a pair of signal line conductors 11, 12 by a resin material 13 by extruding a resin material 13 fused to the pair of signal line conductors 11, 12 which are severally sent out from first and second reels 21, 22; a tension imparting mechanism 10 which imparts tension to the pair of signal line conductors 11, 12; first and second tensiometers 71, 72 as tension detecting parts which detect tension of the pair of signal line conductors 11, 12; and an ECU 9 as a control part which controls tension of the tension imparting mechanism 10, in which the ECU 9 controls tension of the pair of signal line conductors 11, 12 so as to equalize the tension.SELECTED DRAWING: Figure 1 |
