<P>PROBLEM TO BE SOLVED: To provide a noise absorbing device that can be attached in the length direction of an electric wire across a wide range, regardless of use of a ferrite sintered compact. <P>SOLUTION: A noise absorbing device 1 is attached around an electric wire C to attenuate noises propagated along the electric wire C. The noise absorbing device 1 includes a band-like substrate 3 and a plurality of ferrite members 5 bonded to the band-like substrate 3. The plurality of ferrite members 5 are formed by bonding a ferrite sintered compact 5a formed in thin plate to the band-like substrate 3 and then splitting it along a division line 5b tilted from the length direction of the band-like substrate 3 as well as along division line 5c parallel to the length direction of the band-like substrate 3. The noise absorbing device 1 constituted like this is wound around the electric wire C while the axial direction of the electric wire C is parallel to the division line 5b, allowing its spiral attachment on the outer periphery of the electric wire C. <P>COPYRIGHT: (C)2009,JPO&INPIT |
