Abstract: A soft magnetic powder including a first particle group including particles having a particle size of D50 or more and a second particle group including particles having a particle size of less than D50. An average value of circularities of the particles belonging to the first particle group is defined as a first average circularity C1, and an average value of circularities of the particles belonging to the second particle group is defined as a second average circularity C2, and C1
