To effectively restrain the occurrence of electromagnetic induction in the other electric wire or a cable despite the frequency of an electric current flowing in the electric wire, and without providing a special magnetic field shielding layer.

This cable is arranged of a first electric wire where an electric current, varying in point of time, is flowing; and a second electric wire where an electric current having a reverse direction to the electric current flowing in the first electric wire, is flowing. At this time, the first electric wire is divided into two electric wires having conductors C1 and C2 respectively, and the second electric wire is divided into two electric wires having conductors C1' and C2' respectively; and also the respective electric wires are arranged so that the mating divided first and second electric wires can be positioned orthogonally, and the like, to make mating magnetic fields, formed by electric currents flowing in the respective electric wires, can be canceled.
