Abstract
Disclosed herein is a common mode filter including: a coil part including a conductor coil provided in an insulating part; a plurality of external electrodes provided on the insulating part while being electrically connected to the conductor coil; and a magnetic material part provided in a region between the plurality of external electrodes on the insulating part. By this configuration, impedance characteristics of the common mode filter may be improved.
