Abstract
A noise suppression cable includes an electrical wire, a first magnetic material including a pair of first surfaces formed along an axis direction of the electrical wire and a convex portion projecting from the first surfaces, and a second magnetic material including a pair of second surfaces disposed on a periphery of the electrical wire, the pair of the second surfaces contacting the pair of the first surfaces such that a tubular shape is formed by the first and second magnetic materials. The first magnetic material and the second magnetic material are configured to generate a compression stress in the convex portion of the first magnetic material by receiving an external force so as to reduce a relative permeability of the convex portion.
