Abstract
A magnetic material is provided which includes a discrete phase including grains made of a first substance which comprises a magnetic metal; and a continuous phase including a thin coating film made of a second substance which comprises a dielectric or insulating substance. The thin coating film is formed on the surface of the grains and has a mean thickness smaller than the mean particle size of the grains. The grains are separated substantially from each other by the thin coating film.
