A resin including magnetic powder is provided on the uppermost insulation layer and the regions where the insulation layers have been removed, and a second magnetic substrate is bonded through a bonding layer.

Abstract: A structure body having the constitution in which the crystals of a brittle material such as a ceramic, a metalloid and the like and the crystals or the microstructures (the microstructure bodies composed of amorphous metal layers and an organic substance) of a ductile material such as a metal and the like are dispersed, the structure bodies (the portion composed of the brittle material) are polycrystalline, the crystals constituting the structure bodies substantially lack the crystalline orientation, and boundary layers composed of glassy substances are substantially absent in the boundary face between the crystals. It is thereby possible to obtain a structure body having novel characteristics, composed of a brittle material and a ductile material, without involving a heating/sintering process.
