PROBLEM TO BE SOLVED: To provide a ferrite composition having satisfactory initial magnetic permeability and superposed direct current characteristic, also relatively excellent in the temperature characteristic of the initial magnetic permeability and further enabling low temperature firing, and an electronic component having the ferrite composition.SOLUTION: This ferrite composition includes: a main component having 46.0 to 49.8 mol% of iron oxide in terms of FeO, 5.0 to 14.0 mol% of copper oxide in terms of CuO and 8.0 to 32.0 mol% of zinc oxide in terms of ZnO, and the remainder is composed of nickel oxide; and as subcomponents, with respect to 100 wt.% of the main component, 0.5 to 6.0 wt.% of silicon oxide in terms of SiOand 0.01 to 2.0 wt.% of boron oxide in terms of BO. Further, as a subcomponent, 0.01 to 0.17 wt.% of potassium oxide in terms of KO may be included. Further, as a subcomponent, 0.3 to 2.0 wt.% of tin oxide in terms of SnOmay be included. |
