Soft magnetic alloy powder, magnetic core, magnetic component, and electronic device

The present invention provides a soft magnetic powder for obtaining a core having excellent DC superposition characteristics, a magnetic core including the soft magnetic powder, a magnetic component, and an electronic device. The soft magnetic alloy powder includes at least first particles, second particles, and third particles, each of which is composed of a soft magnetic material. The ratio of the powder density to the density calculated from the composition ratio of the soft magnetic alloy powder is 90% or more and 99.5% or less. Assuming virtual two-dimensional coordinates in which the volume-based median diameter is defined as the horizontal axis and the relative powder density obtained by dividing the powder density of each of the first to third particles by the powder density of the third particle is defined as the vertical axis; the relationship between the volume-based median diameter of each of the first to third particles and the relative powder density is drawn in the virtual two-dimensional coord
