There can be provided an NiCuZn-based ferrite material containing , as main components, iron oxide, copper oxide, zinc oxide and nickel oxide in predetermined amounts as main components and, as additional components, cobalt oxide and bismuth oxide, and either silicon oxide and magnesium oxide, or talc in predetermined amounts. The ferrite material is inexpensive, has high initial permeability and excellent stress resistance, and exhibits a small inductance change caused by a compressive stress and a gentle change in permeability along with a change in temperature.
