Abstract
A sintered material contains Fe in an amount of from 8 mol % to 37 mol % in terms of Fe2O3, Zn in an amount of from 30 mol % to 60 mol % in terms of ZnO, Cu in an amount of from 1 mol % to 7 mol % in terms of CuO, Ni in an amount of from 3 mol % to 17 mol % in terms of NiO, and Si in an amount of from 7 mol % to 28 mol % in terms of SiO2. A mole ratio (SiO2/Fe2O3) of the SiO2 to the Fe2O3 is from 0.2 to 3.5. The sintered material contains B in an amount of from 0.05 mol parts to 0.5 mol parts.
