Abstract
In an exemplary embodiment, a magnetic alloy powder is constituted by magnetic grainswhose alloy phaseis coated with an oxide film, wherein: the alloy phasehas 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 filmis 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.
