PURPOSE: A method for manufacturing Mn-Zn ferrite core is provided to obtain a ferrite sintered body having a stable and low power loss in the high frequency area by effectively adding Ti+4 ion to Mn-Zn family ferrite core. CONSTITUTION: A method comprises a first step of adding 0.01 to 5.0 weight percent of FeTiO3(ilmenite), to 51 to 55 mole percent of Fe2O3, 32 to 40 mole percent of one of MnO, MnO2, Mn3O4 and MnCO3, and 6 to 14 mole percent of ZnO, wet mixing and drying the mixture; a second step of calcining the resultant structure at the temperature of 800 to 1100 Deg.C; and a third step of crashing and compacting, and sintering the resultant structure at the temperature of 110 to 1250 Deg.C.
