Abstract

A noise suppression device is disclosed which comprises a toroid-shaped device comprising an amorphous magnetic alloy ribbon wound with plural turns, or ring-shaped pieces formed from an amorphous magnetic alloy ribbon and laminated in plural number, and a through-hole through which an electrical line or lead is inserted, and having a value of Do satisfying the relation of L<Do.ltoreq.5L when an average diameter of said device is Do, provided that the average diameter is an arithmetic mean value of the outer diameter of the device and the diameter of the through-hole, and the largest length at a cross section of said line or said lead, L, is smaller than the diameter of the through-hole. The noise suppression device according to this invention is improved in heat-dissipation properties with a great decrease in breakage, and has a superior noise suppresion effect.
