Abstract
Provided is a flaky soft magnetic powder composed of an Fe—Si—Al alloy containing Si: 5.5 to 10.5 mass %, Al: 4.5 to 8.0 mass %, and Fe and incidental impurities: balance, wherein the flaky powder exhibits a ratio (D/TD) of 35 to 92 where Drepresents the average particle size (μm) of the powder and TD represents the tap density (Mg/m) of the powder, and the flaky powder exhibits a coercive force of 239 to 479 A/m as measured under application of a magnetic field in an in-plane direction of the flaky powder. The flaky soft magnetic powder exhibits superior sheet formability and has high magnetic permeability.
