Kind Code:

Abstract:

[Problem] To provide a noise current absorber capable of stabilizing and maintaining a state in which divided magnetic bodies abut. [Solution] A noise current absorber provided with a pair of divided magnetic bodies obtained by dividing a ring-shaped magnetic body equally into open rings, and a pair of containers in which it is possible to contain the divided magnetic bodies. In the current noise absorber, the pair of containers are joined so that the pair of divided magnetic bodies abut and form a ring shape. The pair of containers each have a plurality of springs that contact with the outer circumferential surface of the divided magnetic bodies and bias the divided magnetic bodies in a first direction parallel with the joining direction of the pair of containers. The plurality of springs include: a metal first spring disposed in the center area of the bottom surface of the containers, the bottom surface facing the divided magnetic bodies; and a pair of resin second springs disposed on either side of the first spring in a second direction orthogonal to both the first direction and the central axis direction of the ring-shaped magnetic body formed by abutting the pair of divided magnetic bodies.
