Patent ID: 8416051

Claim:
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 the oxide film is a film formed by oxidization of the metal grains and bonding the metal grains, which film is constituted by an oxide of the Fe—Si—M soft magnetic alloy of the metal grains, and the mol ratio of the metal element denoted by M relative to the Fe element in the oxide film is greater than the mol ratio of the metal element denoted by M relative to the Fe element in the metal grains; and wherein there are bonding portions via the oxide film formed on the surface of adjacent metal grains and bonding portions of metal grains bonding together where the oxide film is not present.
