Abstract: It is intended to improve magnetic saturation characteristics of magnetic composite bodies containing metal magnetic particles and insulating fine particles.
A magnetic composite body contains a first metal magnetic particle and a second metal magnetic particle, and fine particles are in contact with the first and second metal magnetic particles. The fine particles are insulating and non-magnetic particles. A first oxide film is provided on the surface of the first metal magnetic particle, and a second oxide film is provided on the surface of the second metal magnetic particle.
