Abstract
A common mode noise filter includes a nonmagnetic layer, first and second magnetic layers sandwiching the nonmagnetic layer between the magnetic layers and contacting the nonmagnetic layer, a plane coil provided between the first and second magnetic layers and contacting the nonmagnetic layer, and an external electrode connected electrically with the plane coil. The first and second magnetic layers include a magnetic oxide layer and an insulator layer provided on the magnetic oxide layer. The insulator layer contains glass component. This common mode noise filter has a large bonding strength between the external electrode and the insulator layer.
