PURPOSE:To gain sufficiently high noise suppressing effect of the title magnetic body tube even if the component size is miniaturized by a method wherein said tube is multilayer structured of alternately laminated layers having magnetic body and non-magnetic insulating layers. CONSTITUTION:A cylindrical magnetic body 1 is multilayer structured of alternately laminated magnetic layers 2 and non-magnetic insulating layers 3. Thus, the effect of miniaturizing the component size can be brought about in order to get the impedance value in the same level as that of conventional components, i.e., the noise suppressing effect. Furthermore, the more the laminated layer number and the longer the magnetic body tube, the higher the noise suppressing effect. |
