Abstract
Disclosed herein is a method of manufacturing a noise removing filter, including preparing at least one conductive pattern, an insulating layer for covering the at least one conductive pattern, and a lower magnetic body including input/output stud terminals for electrically inputting and outputting electricity to and from the at least one conductive pattern; disposing a recognizable portion on upper surfaces of the input/output stud terminals; disposing an upper magnetic body on the recognizable portion and the insulating layer; polishing the upper magnetic body; and removing the recognizable portion such that a level of an upper surface of the upper magnetic body is higher than levels of the upper surfaces of the input/output stud terminals.
