<P>PROBLEM TO BE SOLVED: To provide an oxide magnetic material capable of attaining improved DC superposition characteristics without suffering from a lowered sintering density and to provide a laminated inductor using the oxide magnetic material. <P>SOLUTION: The oxide magnetic material comprises a sintered compact having a composition in which the principal component comprises 44 to 47 mol% Fe<SB>2</SB>O<SB>3</SB>, 5 to 13 mol% CuO, and 15 to 23 mol% ZnO with the balance substantially consisting of NiO, and the subsidiary component comprises 0.1 to 0.5 wt.% Mn<SB>2</SB>O<SB>3</SB>and having an average crystal grain diameter of 0.7 to 1.2 μm. It is desirable that the sintered compact has a principal component comprising 45.5 to 47.0 mol% Fe<SB>2</SB>O<SB>3</SB>, 5 to 10 mol% CuO, and 16 to 20 mol% ZnO with the balance substantially consisting of NiO and that the average crystal grain diameter is 0.85 to 1.1 μm. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
