Abstract

The present invention discloses a filter for removing noise, which includes: a lower magnetic body; an insulating layer disposed on the lower magnetic body and including at least one conductor pattern; input and output stud terminals electrically connected to the conductor pattern for electrical input and output of the conductor pattern; and an upper magnetic body consisting of an inner upper magnetic body including ferrite powder with a size corresponding to the interval between the input and output stud terminals and an outer upper magnetic body including ferrite powder with a size corresponding to the interval between the input and output stud terminals and an outer surface of the lower magnetic body. According to the present invention, it is possible to implement a coil part with high performance and characteristics by increasing permeability and improving impedance characteristics through simple structure and process.
