PROBLEM TO BE SOLVED: To realize an oxide magnetic material capable of materializing high initial permeability, at the same time as high impedance characteristic. SOLUTION: This oxide magnetic material contains main components of 51.5 to 54.0 mol% Fe2O3, 24.0 to 28.0 mol% MnO, and a remaineder ZnO, and sub-components of 0.005 to 0.025 wt.% SiO2, 0.02 to 0.07 wt.% CaO, and 0.01 to 5.0 wt.% CuO, and furthermore 0.005 to 0.03 wt.% Bi2O3. |
