In a magnetic body including magnetic particles that contain an FeNi ordered alloy having an L1-type ordered structure, the magnetic particles individually have a flat shape in which a major axis and a minor axis shorter than the major axis intersect each other, and a flat surface along the major axis is larger than a side surface along the minor axis. An easy magnetization axis of the L1-type ordered structure lies along the flat surface.
