A ferrite composition includes a main component having 46.0 to 49.8 mol% of an iron oxide in terms of Fe 2 O 3 , 5.0 to 14.0 mol% of a copper oxide in terms of CuO and 8.0 to 32.0 mol% of a zinc oxide in terms of ZnO, and a remainder of the main component is composed of a nickel oxide; and as subcomponents, with respect to 100 wt% of the main component, 0.5 to 6.0 wt% of a silicon oxide in terms of SiO 2 and 0.01 to 2.0 wt% of a boron oxide in terms of B 2 O 3 . Further, as a subcomponent, 0.01 to 0.17 wt% of potassium oxide in terms of K 2 O or 0.3 to 2.0wt% of tin oxide in terms of SnO 2 may be included. According to the present invention, the ferrite composition having good initial permeability, good superposed direct current characteristic and comparatively good temperature characteristic of the initial permeability, and achieving low temperature firing; and an electronic component having the ferrite composition can be provided. |
