Abstract
An insulation-coated soft magnetic metal powder (1) includes: soft magnetic metal particles (2) having an average equivalent circle diameter of 10 μm to 100 μm; and an insulation layer (3) formed on a surface of each of the soft magnetic metal particles (2). The insulation layer (3) contains an oxide including Zr element. In the insulation-coated soft magnetic metal powder (1), when the oxide is measured at 25° C. by XRD, a strongest peak is a cubic peak or a tetragonal peak, and an intensity of a monoclinic peak is not greater than one-tenth of an intensity of the strongest peak.
