In NiMnZn based ferrite, main components range within the scopes of Fe2O3=53 to 59 mol %, MnO=22 to 41 mol %, ZnO=4 to 12 mol %, and NiO=2 to 7 mol %, and sub-components of said NiMnZn based ferrite range within the scopes of SiO2: 0.005 to 0.03 wt %, CaO: 0.008 to 0.17 wt % and P: 0.0004 to 0.01 wt %. |
