Abstract
A magnetic material contains multiple metal grains constituted by soft magnetic alloy and oxide film formed on a surface of the metal grains, which soft magnetic alloy includes Fe and a metal element that oxidizes more easily than Fe, wherein the magnetic material forms a grain compact having first bonding parts where adjacent metal grains are contacted and directly bonded together, second bonding parts where adjacent metal grains are bonded together via the oxide film formed around the entire surface of said adjacent metal grains other than the first bonding parts, and voids formed in an area other than the first and second bonding parts and surrounded by the oxide film.
