PROBLEM TO BE SOLVED: To provide a ferrite material which realizes both of a high Bs value and high magnetic permeability. SOLUTION: The ferrite material essentially consists of oxides having a spinel structure containing Fe as the main component and at least one of Zn, Ni and Cu, in which the proportion of oxides essentially consisting of at least one of Zn, Ni and Cu is specified to <0.01 vol.%. |
