Abstract
A common mode filter is manufactured to include a coil part including an insulation layer and a conductor pattern formed in the insulation layer; and a magnetic substrate coupled to one surface or both surfaces of the coil part. The magnetic substrate includes: an electrostatic absorbing layer made of an electrostatic absorbing material; a magnetic layer provided on one surface or both surfaces of the electrostatic absorbing layer and made of a magnetic material; and an electrode provided between the magnetic layer and the electrostatic absorbing layer and made of a conductive material. Therefore, common mode filter may maintain high efficiency characteristics while preventing an electrostatic discharge phenomenon.
