2. Description of the Related Art Conventionally, there has been known a noise current absorber in which an outer peripheral portion of an electric wire is surrounded by a magnetic material such as ferrite, and the magnetic material absorbs a noise current flowing through the electric wire. There is a case in which a cylindrical magnetic body formed into a shape which is divided into a plurality of sections by a dividing surface including a shaft, and the divided magnetic bodies are respectively fitted into storage portions of a holding case made of synthetic resin. This noise current absorber is used by joining the divided surfaces of each magnetic body to each other so as to surround the outer peripheral portion of the electric wire with the magnetic material, and absorbs a noise current (noise) flowing through the electric wire.

In such a noise current absorbing device, a magnetic flux loop generated by a noise current is formed in a closed magnetic circuit formed of a magnetic material, thereby converting electromagnetic energy into heat energy and absorbing the noise current. Is obtained. Therefore, it is preferable to wind the electric wire around the magnetic body so as to pass through the inside of the closed magnetic circuit formed of the magnetic body a plurality of times, since the noise current can be more effectively absorbed.
