<p>The electromagnetic filter according to the present invention includes a shield opening 102 provided in a shield conductor 101, a plurality of conductive strips 111 connected to the shield conductor 101 at both of two ends for dividing the shield conductor 101 into a plurality of divided openings 112, and a plurality of band-stop filters 113 located on each of the conductive strips 111 at a prescribed interval. By dividing the shield opening 102 into the plurality of divided openings 112, the amount of noise leaking via the shield opening 102 can be suppressed. Each of the band-stop filters 113 prevents a flow of an electric current of a prescribed frequency in each of the conductive strips 111, which would otherwise be caused by a magnetic field of the prescribed frequency passing the shield opening 102, and thus the wireless electric power transmission characteristic which uses coupling of magnetic fields of the prescribed frequency can be prevented from being deteriorated.</p> |
