Abstract
A ferrite sintered body contains from 45.0% by mole to 49.7% by mole Fe in terms of from FeO, 2.0% by mole to 8.0% by mole Cu in terms of CuO, from 25.0% by mole to 45.0% by mole Ni in terms of NiO, and from 1.0% by mole to 20.0% by mole Zn in terms of ZnO, in which when Fe, Cu, Ni, and Zn are converted to FeO, CuO, NiO, and ZnO, respectively, and when the total amount of the FeO, the CuO, the NiO, and the ZnO is 100 parts by weight, the ferrite sintered body contains from 5 ppm to 25 ppm B in terms of elemental B and from 6 ppm to 25 ppm Nb in terms of elemental Nb.
