Provided is a ferrite-polymer nanocomposite, which has high permeability and low loss characteristics at the high-frequency zone and is applicable to electronic equipment such as high-frequency layered chip inductors, wire-wound inductors, transformers, converters, etc. The ferrite-polymer nanocomposite is obtained by dispersing conglomerate of soft magnetic ferrite nanopowder in polymer matrix. The soft magnetic ferrite is any one selected from Mn-Zn, Ni-Zn, Ni-Cu-Zn, Ni-Cu-Co-Zn, Ni-Co, Mg-Zn, Mg-Mn-Zn, Cu-Zn-based spinel ferrites, cobalt-substituted Y type and Z type hexagonal ferrites, and a mixture of two or more thereof. The polymer is any one selected from a thermoplastic resin, a thermosetting resin, and a mixture of two or more thereof. The thermoplastic resin is polyphenylene sulfide, polyamide, polyethylene, polyimide, polysulfone, polyetherether ketone, polystyrene, etc. The thermosetting resin is epoxy resin, phenolic resin, polyimide, diarylphthalate resin, etc.
