Abstract: A composite ferrite composition comprises a magnetic material and a non-magnetic material. A mixing ratio of said magnetic material and said non-magnetic material is 20 wt %:80 wt % to 80 wt %:20 wt %. Ni—Cu—Zn based ferrite is used as the magnetic material. Oxides of Zn, Cu, and Si are at least included in a main component of said non-magnetic material. Borosilicate glass is included in a subcomponent of said non-magnetic material.

Abstract: A ferrite composition comprises a main component and a sub component. The main component is comprised of 25.0 to 49.8 mol % iron oxide in terms of Fe2O3, 5.0 to 14.0 mol % copper oxide in terms of CuO, 0 to 40.0 mol % zinc oxide in terms of ZnO, and a remaining part of nickel oxide. The sub component includes 0.2 to 5.0 wt % silicon oxide in terms of SiO2, 0.10 to 3.00 wt % bismuth oxide in terms of Bi2O3, and 0.10 to 3.00 wt % cobalt oxide in terms of Co3O4, with respect to the main component.
