Zusammenfassung:	To provide ferrite particle powder for electromagnetic wave absorption, which can maintain flexibility and uniformity of physical properties of a sheet even when the sheet is filled with a high volume, and has excellent electromagnetic wave absorption performance in the GHz band. Electromagnetic wave absorption ferrite particle powder, consists of a magnetoplanbite type ferrite represented by the chemical formula: AxFe(12-y)(TizMn(1-z))yO19, where A is at least one selected from Ba, Sr, Ca, and Pb, x is 0.9~1.1, y is 5.0 or less, z is 0.35~0.65, has a compression density of 3.00 g/cm3 or more, and has an average particle size of 0.50~3.0[mu]m determined by the air permeation method (Brane method).
