Abstract
The present invention relates to an Ni—Zn—Cu—Co ferrite sintered plate having a composition comprising 45 to 50 mol % of FeO, 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, all of the molar amounts being calculated in terms of the respective oxides, and a ferrite sintered sheet that is provided on a surface thereof with a groove and further with an adhesive layer and/or a protective layer. The ferrite sintered sheet is capable of exhibiting an increased μ' value of a magnetic permeability while maintaining a small μ″ value of the magnetic permeability.
