<p>In the nonmagnetic Zn-ferrite of the present invention comprising iron oxide and zinc oxide, the content of Fe 2+ is specifically limited. Alternately in the nonmagnetic Zn-ferrite comprising iron oxide and zinc oxide as main components, a given amount of at least 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.</p> |
