PROBLEM TO BE SOLVED: To provide a magnetic ferrite material which is gentle in the temperature change of magnetic permeability, is large in a Q value, is high in mechanical strength, is less changed in inductance with respect to compressive stress and is inexpensive. SOLUTION: This magnetic ferrite material contains, as essential components, iron oxide in a range of 40 to 46 mol% in terms of Fe2O3, zinc oxide in a range of 25.1 to 30 mol% in terms of ZnO, nickel oxide in a range of 10 to 25 mol% in terms of NiO and the balance copper oxide, respectively and contains, as auxiliary components for the essential components, bismuth oxide in a range of <=2 wt.% in terms of Bi2O3 and cobalt oxide in a range of <=0.1 wt.% in terms of Co3O4. |
