<p><P>PROBLEM TO BE SOLVED: To facilitate the adjustment of the gaps of a choke coil, and facilitate the manufacture of the choke coil. <P>SOLUTION: The choke coil has an air-core coils 16a, 16b formed by winding conductors around them, rod-form cores 14a, 14b formed out of a magnetic material and disposed in the respective insides of the air-core coils 16a, 16b, and magnetically permeable covers 18a, 18b so disposed at both the ends of the rod-form cores 14a, 14b as to be contacted with the rod-form cores 14a, 14b which form closed magnetic paths between them and the rod-form cores 14a, 14b. Further, the magnetic permeabilities of the magnetically permeable covers 18a, 18b are made lower than the ones of the rod-form cores 14a, 14b. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
