摘要： The ferrite sintered body of the present invention is a hexagonal Z-type ferrite sintered body having a high permeability and a low anisotropy of permeability, comprising a c-axis-oriented plane in which a degree of orientation fc⊥ is not less than 0.4, said degree of orientation being given as fc⊥=ΣI(HK0)/ΣI(HKL), when I(HKL) is the integrated intensity of a diffraction peak represented by an index (HKL) in an X-ray diffraction pattern of which measurement range is 2θ=20 to 80°, wherein the degree of orientation fc∥ calculated from fc∥=I(0018)/I(110) in an X-ray diffraction is not less than 0.3 in at least two planes which are perpendicular to the aforementioned c-axis-oriented plane and are perpendicular to each other. Where ΣI(HKL) is the sum of integrated intensity of all the diffraction peaks of hexagonal Z-type ferrite.
