Abstract
A ferrite composition includes a main component and an accessory component. The main component includes 18 to 30 mol % of iron oxide in terms of FeO, 4 to 14 mol % of copper oxide in terms of CuO, 0 to 6 mol % of zinc oxide in terms of ZnO, and a remaining part of nickel oxide. The accessory component includes 0.30 to 1.83 pts.wt. of silicon compound in terms of SiO, 2.00 to 10.00 pts.wt. of cobalt compound in terms of CoO, and 1.00 to 3.00 pts.wt. of bismuth compound in terms of BiOwith respect to 100 pts.wt. of the main component. A cobalt compound content in terms of CoOdivided by a silicon compound content in terms of SiOis a value of 5.5 to 30.0.
