Abstract
A differential signal transmission cable has a pair of conductors arranged to be distant from each other and parallel to each other, an insulator covering the pair of conductors, and a shield conductor wound around the insulator. The insulator has an outer periphery shape of a transversal cross section in that a plurality of curved lines with different curvature radiuses are combined. The shield conductor has an inner periphery shape of a transversal cross section in that the plurality of curved lines are combined in accordance with the outer periphery shape of the insulator.
