PROBLEM TO BE SOLVED: To provide a line filter that can be reduced in distribution capacity and can be improved in noise attenuating characteristics over a wide frequency zone from a low frequency band to a high frequency band. SOLUTION: This line filter is provided with windings 11 and 12, cores 21 and 22, and a conductor 3. This filter is also provided with a bobbin 4 having first and second flanges 41 and 42 at both ends and, at the same time, an intermediate flange 40 at the central part. The bobbin 4 also has a core inserting hole 45 penetrated in one direction. The first and the second windings 11 and 12 are wound around the bobbin 4 by commonly using a winding axis and separated from each other in the direction of the winding axis. The cores 21 and 22 are inserted into the core inserting hole 45 of the bobbin 4 passing the winding axis. The conductor 3 is provided on the bobbin 4 at the intermediate flange 40 which becomes the separating section of the first and the second windings 11 and 12. COPYRIGHT: (C)2005,JPO&NCIPI
