Abstract
The soft magnetic material of embodiments includes flattened magnetic metal particles including at least one magnetic metal selected from iron (Fe), cobalt (Co) and nickel (Ni), each of the flattened magnetic metal particles having a thickness of from 10 nm to 100 μm, an aspect ratio of from 5 to 10,000, and a lattice strain of from 0.01% to 10%, and being oriented with magnetic anisotropy in one direction within aligned flattened surface; and an interposed phase existing between the flattened magnetic metal particles and including at least one of oxygen (O), carbon (C), nitrogen (N) and fluorine (F).
