Abstract
Flaky magnetic metal particles of embodiments each have a flat surface and a magnetic metal phase containing iron (Fe), cobalt (Co), and silicon (Si). An amount of Co is from 0.001 at % to 80 at % with respect to the total amount of Fe and Co. An amount of Si is from 0.001 at % to 30 at % with respect to the total amount of the magnetic metal phase. The flaky magnetic metal particles have an average thickness of from 10 nm to 100 μm. An average value of the ratio of the average length in the flat surface with respect to a thickness in each of the flaky magnetic metal particles is fromto. The flaky magnetic metal particles have the difference in coercivity on the basis of direction within the flat surface.
