A noise suppression cable includes an insulated electric wire including an insulator that covers an outer periphery of a conductor wire, and a magnetic tape layer formed by transversely winding a magnetic tape on an outer periphery of the insulated electric wire. A magnetic body constituting the magnetic tape is cut out from a rolled material in such a manner that a width direction of the magnetic tape corresponds to a rolled direction, and the magnetic body has a magnetic property that is different between the width direction and an orthogonal direction to the width direction.
