摘要： The present invention relates to ferrite particles for bonded magnet, having a volume-average particle diameter of 2.1 to 2.7 µm and a particle diameter x90 of 4.3 to 5.4 µm wherein the x90 represents a particle diameter at which a cumulative percentage of particles under sieve (undersize particles) based on a volume thereof is 90%, when determined from a particle size distribution thereof measured by using a laser diffraction type particle size distribution measuring apparatus.
