PURPOSE: A dual mode filter is provided to remove differential mode noise and common mode noise using one element by integrating inductor layers for removing differential mode noises and a filter layer for removing a common mode noise in one element. CONSTITUTION: A dual mode filter includes a first inductor layer (100) in which a plurality of sheets with conductive patterns is laminated for the formation of an inductor; a filter layer (200) in which a plurality of sheets with conductive patterns is laminated and which is put on the top of the first inductor layer; and a second inductor layer (300) in which a plurality of sheets with conductive patterns is laminated and which is put on the top of the filter layer. |
