Abstract:
A magnetic material constituted by a grain-compacted body comprising a plurality of metal grains made of a Fe—Si—M soft magnetic alloy (where M is a metal element more easily oxidized than Fe) and an oxide film formed on the surface of the metal grains; wherein there are bonding portions via the oxide film formed on the surfaces of adjacent metal grains and direct bonding portions of metal grains in locations where the oxide film is not present.
