PROBLEM TO BE SOLVED: To provide a coil for a filter that allows the further integration of inductors through the number of the inductors is increased due to multi-channelization, and can be reduced in the thickness of an apparatus, a mounting area and cost. SOLUTION: First, the coil for a filter is constituted of a coil element, a ring core which accommodates the coil element, and a base on which an external terminal is arranged. In the coil element, a first coil and a second coil are wound around the spool of a core so that respective winding shafts are perpendicularly intersected. COPYRIGHT: (C)2005,JPO&NCIPI
