摘要：
In the nonmagnetic Zn-ferrite of the present invention comprising iron oxide and zinc oxide, the content of Fe2+ is specifically limited. Alternately in the nonmagnetic Zr-ferrite comprising iron oxide and zinc oxide as main components, a given amount of at lease one metal oxide selected from the group consisting of manganese oxide, nickel oxide and magnesium oxide is contained. It is thus possible to provide a nonmagnetic Zn-ferrite that can have high resistivity without containing Cu.
