<P>PROBLEM TO BE SOLVED: To provide an effective means of suppressing leakage flux from a coil and to provide ferrite particles and a ferrite-resin composite composition capable of maintaining its stable composition even in long-term storage and in continuous use particularly when a composition comprising ferrite particles dispersed in a resin is provided. <P>SOLUTION: The ferrite particles have ≤5 μm average grain diameter, 25-45 μm volume average particle diameter D50, ≥0.08 m<SP>2</SP>/g BET specific surface area and ≤2.1 g/cm<SP>3</SP>bulk density. The ferrite-resin composite composition uses the ferrite particles. <P>COPYRIGHT: (C)2003,JPO |
