Abstract: A soft magnetic material comprising a soft magnetic metal powder and a resin, wherein the soft magnetic metal powder is constituted from a particle group α and group β, when IA is a peak intensity of the particle group α, IB is a peak intensity of the particle group β, and IC is a minimum intensity present between the particle group α and group β, then an intensity ratio IC/IA satisfies 0.10 or less and an intensity ratio IA/IB satisfies 1.2 or more and 3.0 or less, the particle group α having a maximum peak intensity in a size distribution of the soft magnetic metal powder, the particle group β having an peak intensity which is the second largest to the particle group α, and a peak particle size PA of the particle group α is larger than a peak particle size PB of the particle group β.
