Abstract

See full text

A magnetic base body relating to one embodiment of the present invention includes a main body and an oxide film formed on the surface of the main body. The main body includes an oxide phase containing Si and a plurality of metal magnetic particles bound via the oxide phase. In the metal magnetic particles, Fe accounts for 98.5 wt % or more. When an XRD diffraction pattern of the magnetic base body is observed, a ratio Ia/Ib is 10 or more where Ia denotes an integrated intensity of peaks derived from the (220) plane of Fe2O3 and Ib denotes an integrated intensity of peaks derived from the (104) plane of Fe3O4.
