To provide an easily sinterable low loss Ni-Zn-based ferrite material in which core loss is low to be ≤400 kW/m3, resistance is high to be ≥108 Ωcm at the room temperature, magnetic permeability is high to be ≥1,200, Bs is ≥3,000 Gauss, and Tc is ≥150°C.

The ferrite material contains a prescribed quantity of Fe2O3, CuO, ZnO and MnO and has 1-30 μm average crystal grain diameter and ≥5.1 g/cm3 sintered density.
