Abstract

The present invention discloses a filter for removing noise, which includes: a lower magnetic body; an insulating layer provided on the lower magnetic body and including at least one conductor pattern; and an upper magnetic body including a primary ferrite composite provided on the insulating layer and a secondary ferrite composite provided on the primary ferrite composite to cover a pore formed on a surface of the primary ferrite composite, and a method of manufacturing the same. According to the present invention, it is possible to implement a filter for removing noise with high performance and characteristics by increasing magnetic permeability and improving impedance characteristics through simple structure and process.
