Embodiment Construction
[0014] Hereinafter, the NiCuZn-based ferrite (oxide magnetic material) of the present invention will be described in detail.
[0015] For the substantial main component in the NiCuZn system ferrite of the present invention contains: Fe 2 o 3 Contains 45.0-49.0 mol% of iron oxide (especially preferably 47.0-48.8 mol%); 5.0-14.0 mol% of copper oxide as CuO (especially 7.0-12 mol%); 1.0-32.0 mol of zinc oxide as ZnO % (particularly preferably 14.0 to 28.0 mol%); NiO contains nickel oxide as the balance mol%.
[0016] Furthermore, in the NiCuZn-based ferrite of the present invention, with respect to the main component, as a subcomponent, Bi 2 o 3 Calculated, bismuth oxide is greater than 0.25% by weight, 0.40% by weight or less (especially preferably 0.26~0.33% by weight); 2 In total, tin oxide is 1.00 to 2.50% by weight (especially preferably 1.00 to 2.20% by weight).
[0017] For the composition range of the above-mentioned main components, if iron oxide (Fe 2 o 3 ) conte...
