Noise filter

Abstract

A noise filter includes a plurality of magnetic sheets stacked one on another. The magnetic sheets are baked to form a layered product. A transmission line is arranged between the second and third magnetic sheets. The transmission line extends linearly in the longitudinal direction of the layered product. Two ground conductors have the second and third magnetic sheets therebetween. Signal electrodes connected to both ends of the transmission line are arranged adjacent to both ends, in the longitudinal direction, of the layered product. Grounding electrodes connected to the ground conductors are arranged in the middle positions, in the longitudinal direction, of the layered product. With the ground conductors being grounded, a signal passes through the transmission line, thus attenuating high-frequency noise using heat dissipation by the four magnetic sheets.
