<P>PROBLEM TO BE SOLVED: To provide a ferrite part capable of suppressing peeling of a protective layer. <P>SOLUTION: A ferrite component 1 comprises a sintered ferrite plate F1, and a protective layer S1 which is bonded to the first main surface 10 of the sintered ferrite plate to cover the first main surface 10. The first main surface 10 has an arithmetic mean height (Ra) of 0.15-1.0 μm. The first main surface 10 has an appropriately continued roughness. So, if the ferrite component 1 is bent, the deflected part 14 of the protecting layer S1 that is caused by bending spreads between protrusions on the first main surface 10. The protecting layer S1 will no longer be released and lifted. As a result, releasing of the protecting layer S1 is suppressed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
