<p>A ferrite material in which Bi 2 O 3 is added at 6% by weight or less, and preferably 4% by weight or less, to a ferrite of Li-Zn-(Mn, Fe) containing a specified amount of Mn. In the ferrite material, change of magnetic permeability under high external stress is extremely small, and a core loss under a compression stress is small. By using this ferrite material, an inductor and transformer having small loss even in a state of being molded with resin can be obtained.</p> |
