Abstract
A common mode noise filter includes a first insulating layer, a first coil conductor on an upper surface of the first insulating layer, a second coil conductor on a lower surface of the first insulating layer, a second insulating layer on the upper surface of the first insulating layer to cover the first coil conductor, a third insulating layer on a lower surface of the second insulating layer to cover the second coil conductor. The first insulating layer contains glass and inorganic filler, and contains pores dispersed therein. The second insulating layer covers the first coil conductor, contains glass and inorganic filler, and contains pores dispersed therein. The third insulating layer covers the second coil conductor, contains glass and inorganic filler, and contains pores dispersed therein. This common mode noise filter has excellent high-frequency characteristics at a high yield rate.
