A ferrite material of the present invention is configured such that 0.05 to 1.0 wt % of bismuth oxide in terms of Bi2O3, 0.5 to 3.0 wt % of tin oxide in terms of SnO2, and 30 to 5000 wt ppm of chromium oxide in terms of Cr2O3 are added to a predetermined main component mixture composition. Therefore, it is possible to achieve an improvement in DC bias characteristics, an improvement in temperature characteristics of initial magnetic permeability, and an improvement in resistivity and further achieve an improvement in burned body strength, particularly in burned body flexural strength (bending strength).
