Abstract
A plurality of flaky magnetic metal particles have an average thickness of 10 nm to 100 μm, each of the particles having a flat surface; a magnetic metal phase containing at least one element selected from the group consisting of Fe, Co, and Ni; and a difference in coercivity on the basis of direction within the surface, the average value of the ratio of the average length within the surface with respect to the thickness being from 5-10,000. The particles include a particle having at least one of a crack in a thickness direction having a depth equivalent to 10% or more of the thickness of the particle and a width shorter than the depth, and a crack in a direction parallel to the surface having a length equivalent to 10% or more of the thickness of the particle and a width shorter than the length.
