ABSTRACT:
A ferrite core comprising a sintered oxide containing at least 48.6 to 53.9 mol % of Fe on Fe2O3basis, 12.3 to 35.2 mol % of Ni on NiO basis and 16.4 to 37.0 mol % of Zn on ZnO basis as metal elements, and contains a crystal phase comprising two or more kinds of solid solutions selected from NiFe2O4, ZnFe2O4and FeFe2O4, wherein full width at half maximum of a diffraction peak, of crystal phase of which diffraction angle 2θ is in a range from 34.6 to 36.4° as measured by X-ray diffraction analysis using Cu—Kα beam, is 0.4° or less.
