Beschreibung
Zusammenfassung:	A common mode noise filter is provided with a nonmagnetic layer; first and second magnetic layers arranged on the nonmagnetic layer by sandwiching the nonmagnetic layer; a planar coil, which is arranged between the first magnetic layer and the second magnetic layer and is brought into contact with the nonmagnetic layer; and an external electrode electrically connected with the planar coil. The first and the second magnetic layers are provided with an oxide magnetic layer, and an insulating layer which is provided on the oxide magnetic layer and includes a glass component. In the common mode noise filter, bonding strength between the external electrode and the insulating layer can be increased.
