Abstract: A soft magnetic alloy powder includes a first pulverized powder which has a particle diameter of 20 μm or more, a value of major diameter/minor diameter of 1.2 or more and 1.8 or less, and a flat plate shape, and a second pulverized powder which has a particle diameter of less than 3 μm, a value of major diameter/minor diameter of 1.1 or more and 1.6 or less, and a flat plate shape. A production method of a soft magnetic alloy powder, includes first processing of processing a soft magnetic alloy ribbon into a coarse powder, and second processing of pulverizing the coarse powder with a pulverizer.
