Abstract
A ferrite material and an electronic component which employs sintered ferrite formed from the ferrite material. The ferrite material is obtained by adding, as minor ingredients, 0.06-0.50 parts by weight of bismuth oxide in terms of Bi2O3, 0.11-0.90 parts by weight of titanium oxide in terms of TiO2, and 0.06-0.46 parts by weight of barium oxide in terms of BaO to a ferrite powder comprising iron oxide, copper oxide, zinc oxide, and nickel oxide as major ingredients. The weight ratio among the bismuth oxide, the titanium oxide, and the barium oxide is as follows: when the proportion of the bismuth oxide in terms of Bi2O3 is taken as 1.00, then the proportion of the titanium oxide in terms of TiO2 is 1.08-2.72 and that of the barium oxide in terms of BaO is 0.72-1.20.
