<P>PROBLEM TO BE SOLVED: To provide a coil component which works quietly even when used within the human audible frequency range. <P>SOLUTION: A coil component comprises a triple layered compound magnetic core laminating closed magnetic circuit cores 4 at each of upper and lower layers of a C-shaped core 5 in the thickness direction. A magnetic gap of the C-shaped core 5 is firmly fixed by being confined with the upper and lower layers of the closed magnetic circuit cores 4, thus a vibration yielded by a magnetic attraction force between magnetic substances facing the magnetic gap part is suppressed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
