Abstract
A three-terminal type noise filter has a lead terminal of substantially U-like shape, two magnetic substance cores and a rectangular-plate-like-shaped capacitor which have surfaces which are parallel, the cores being inserted onto both legs of the lead terminal, the capacitor being disposed between the two magnetic substance cores, so that both the cores regulate movement of the capacitor, thereby improving positioning accuracy for the lead terminal and capacitor and raising the reliability of the filter characteristic. Also, one electrode of the capacitor and the head of the lead terminal are electrically connected with each other, a ground lead terminal connected to the other electrode of the capacitor is positioned between the two legs of the lead terminal, and the capacitor is disposed between the cores, thereby enabling the filter to be made small-sized as a whole.
