PROBLEM TO BE SOLVED: To provide a measurement device that can accurately measure the distance between the centers of the conductors of cables for differential signal transmission without limiting the material of an insulation body coating the conductor, in a non-destructive and non-contact manner, and can assure low skew of the cable for differential signal transmission by performing feedback on the basis of the measurement result and controlling the distance between the centers of the conductors, and provide a manufacturing method of the cable for differential signal transmission.SOLUTION: The manufacturing method of the cable for differential signal transmission includes a coating process of coating at least a pair of conductors 4 separated from each other and extending in parallel in a longitudinal direction with an insulation body, and a measurement process of measuring the distance between the centers of at least the pair of conductors 4 through the insulation body at a plurality of places in the longitudinal direction after the coating process. |
