Abstract
Provided is a ferrite particle powder for electromagnetic wave absorption that can maintain flexibility and uniformity of physical properties of a sheet even when the sheet is highly filled with the ferrite particle powder and is excellent in electromagnetic wave absorbing performance in a GHz band. The ferrite particle powder is a ferrite particle powder for electromagnetic wave absorption, the ferrite particle powder containing magnetoplumbite-type ferrite represented by a chemical formula of AxFe(12-y)(TizMn(1-z))yO19, where A is at least one selected from Ba, Sr, Ca, and Pb, x is 0.9 to 1.1, y is 5.0 or less, and z is 0.35 to 0.65, and the ferrite particle powder having: a compressed density of 3.00 g/cm3 or more; and an average particle diameter of 0.50 to 3.0 μm determined by an air permeability method (Blaine method).
