Zusammenfassung:	PROBLEM TO BE SOLVED: To provide ferrite particle powder for bonded magnets, capable of obtaining a bonded magnet compact with good mechanical strength and superior magnetic characteristics of molded products, a resin composition for the bonded magnets, and a bonded magnet compact, such as a magnet roll that uses the ferrite particle powder and the composition. SOLUTION: Ferrite particle powder for bonded magnets, a resin composition for the bonded magnets, and a magnet roll have a particle size distribution, with a mean volume diameter controlled from 2.1 μm to 2.7 μm and the standard deviation σ of the particle size distribution controlled from 1.4 to 1.9.
