Provided is a NiZn ferrite which has excellent productivity and is capable of suppressing an increase in the rate of change in relative complex permeability with respect to temperature. The present invention relates to a copper-based alloy which contains 47.50 to 48.60 mol% of Fe in terms of Fe2O3, 29.00 to 30.11 mol% of Zn in terms of ZnO, 5.50 to 6.50 mol% of Cu in terms of CuO, and 14.80 to 18.00 mol% of Ni in terms of NiO, the total amount of Fe2O3, ZnO, NiO and CuO being 100 mol%, with the total amount of Fe, Zn, Ni and Cu in terms of Fe2O3, ZnO, NiO and CuO being 100 parts by mass, with Mn in terms of Mn3O4 being 0.100 to 0.400 parts by mass, Ti being 0.050 to 0.500 parts by mass, Ca being 0.025 parts by mass or less in terms of CaO being 0.025 parts by mass or less in terms of SiO2 being 0.250 parts by mass or less in terms of SiO2.
本发明提供一种生产率优异、能够抑制相对复磁导率对于温度的变化率增加的NiZn系铁氧体。其包含以Fe2O3换算计为47.50～48.60mol％的Fe、以ZnO换算计为29.00～30.11mol％的Zn、以CuO换算计为5.50～6.50mol％的Cu、以NiO换算计为14.80～18.00mol％的Ni，Fe2O3、ZnO、NiO、CuO的合计量为100mol％，其中，在以Fe2O3、ZnO、NiO、CuO换算计将Fe、Zn、Ni、Cu的合计量设为100质量份时，Mn以Mn3O4换算计为0.100～0.400质量份，Ti以TiO2换算计为0.050～0.500质量份，Ca以CaO换算计为0.025质量份以下，Si以SiO2换算计为0.250质量份以下。
