<p><P>PROBLEM TO BE SOLVED: To solve the problem that a coil component having a high self-resonance frequency fr cannot be easily reduced in size. <P>SOLUTION: An electric wire is wound and folded back several times to form a multilayer coil 13. An insulation layer 16 is disposed between adjacent layers which have a large difference in the number of turns of the electric wire (a large potential difference), rather than those which have a small difference. <P>COPYRIGHT: (C)2004,JPO</p> |
