Ferrite sintered plate and ferrite sintered sheet
The present invention relates to: a Ni-Zn-Cu-Co ferrite sintered plate characterized by having a chemical composition composed of, in terms of oxide contents, 45 to 50 mol% of Fe2O3, 10 to 25 mol% of NiO, 15 to 36 mol% of ZnO, 2 to 14 mol% of CuO and 0.1 to 3.5 mol% of CoO; and a ferrite sintered sheet characterized by being formed by providing a groove on the surface of the ferrite sintered plate and then additionally providing an adhesive layer and/or a protective layer on the groove-formed surface. The ferrite sintered sheet according to the present invention has such a property that the value of mu' can be increased while keeping the value of mu" at a low level with respect to magnetic permeability.
