In an exemplary embodiment, a
magnetic alloy powder is constituted by magnetic grains 100 whose
alloy phase 1 is coated with an
oxide film 2, wherein: the
alloy phase 1 has a
Fe content of 98 percent by
mass or higher and also contains Si and at least one type of non-
Si element that oxidizes more easily than Fe (element M); and the
oxide film 2 is such that, at the location where the content of Si as expressed in percentage by
mass is the highest according to the element distributions in the direction of film thickness, this content of Si is higher than the content of Fe, and also higher than the content of element M, at this location. The
magnetic alloy powder has a high
Fe content and also offers excellent insulating property.
