PROBLEM TO BE SOLVED: To obtain a low-loss oxide magnetic material that has a low loss, high flux density, and improved safety. SOLUTION: In an Ni-Zn-Cu-family low-loss oxide magnetic material that uses Fe2O3, ZnO, and CuO as the main constitutents, at least one type of admixture of Na2O, K2O, Rb2O, and Cs2O is set to a low-loss oxide magnetic material of 10 wt.% or less (where, 0 is excluded). |
