FILTER FOR REMOVING NOISE

摘要

PURPOSE: A noise removing filter is provided to increase magnetic permeability, thereby improving the characteristics of impedance and the shielding properties against electromagnetic waves or the likes. CONSTITUTION: A noise removing filter comprises a lower magnetic substrate(110), a coil layer(120), an upper magnetic substrate(130), and a magnetic permeability reinforcing layer(140). The coil layer is disposed on the lower magnetic substrate and includes at least one conductive pattern and an insulating layer covering the conductive pattern. The upper magnetic substrate is disposed on the coil layer. The magnetic permeability reinforcing layer is provided on one of the lower magnetic substrates and the upper magnetic substrate, of which the magnetic permeability is lower than that of the other.
