PROBLEM TO BE SOLVED: To provide a Mn-Zn ferrite having a specific resistance over an order of 1 Ωm and also a low magnetic core loss even in a high frequency zone over 1 MHz. SOLUTION: This Mn-Zn ferrite consisting of a basic component composition of 44.0-49.8 mol% Fe2O3, 6.0-15.0 mol% ZnO (provided that 15.0 mol% is excluded), 0.1-4.0 mol% 1 kind or 2 kinds out of TiO2 and SnO2 and rest of MnO, is obtained by suppressing Fe2O3 in a lower range than 50 mol% which is a stoichiometric composition, adding TiO2 or SnO2 in an optional amount and making <10 μm mean crystal particle diameter. |
