A ferrite composition composed of a main component including 26 to 46 mol % of an iron oxide in terms of Fe2O3, 4 to 14 mol % of a copper oxide in terms of CuO, 0 to 26 mol % of a zinc oxide in terms of ZnO, and a residue of 40.0 mol % or more of a nickel oxide in terms of NiO. The ferrite composition, with respect to 100 parts by weight of the main component, is also composed of a subcomponent including 0.8 to 10.0 parts by weight of a silicon compound in terms of SiO2, 1.0 to 15.0 parts by weight of a cobalt compound in terms of Co3O4, and 0.7 to 30.0 parts by weight of a bismuth compound in terms of Bi2O3. A value of the cobalt compound content in terms of Co3O4 divided by the silicon compound content in terms of SiO2 is 0.4 to 5.5. |
