Abstract
One object is to provide a magnetic body having a high mechanical strength. A magnetic body according to one embodiments of the present invention includes: first particles of a first alloy containing Fe and Cr; second particles of a second alloy containing at least one of Al or Mn; and bonding portions containing at least one of Al oxide or Mn oxide, the bonding portions bonding the first particles to each other. The bonding portions containing at least one of Al oxide or Mn oxide increase the mechanical strength of the magnetic body.
