Abstract:
1. A magnetic material containing 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 at least one alloy 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, and 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 wherein the at least one alloy element that oxidizes more easily than Fe is contained in the soft magnetic alloy in total in an amount of 2.5 to 22 percent by weight, wherein the at least one alloy element that oxidizes more easily than Fe includes a metal element which is contained in the soft magnetic alloy in an amount of 2.0 to 15 percent by weight.
