The invention provides a method for manufacturing a soft magnetic material, wherein an Fe—Si alloy powder is heated in a weakly oxidizing atmosphere to form a SiO2 oxide film on the surface, and the powder is then press-molded and fired in a weakly oxidizing atmosphere to obtain a sintered product. By performing the surface oxidizing step in a weakly oxidizing atmosphere such as water vapor, Si is selectively oxidized to form a thin oxide film with high electrical resistance. Furthermore, by firing the molded product in a weakly oxidizing atmosphere, the sintering can be performed while the oxide film, in which cracks and the like are generated at the press-molding, is repaired.

摘要:
A soft magnetic core is substantially cylindrical and a linear-shaped coil conductor is inserted through a hole in the central portion of the soft magnetic core. A hard magnetic material sheet has areas which are magnetized in a thickness direction thereof and the areas are arranged in strips so that a magnetization direction of adjacent strips is mutually opposite. The hard magnetic material is wound on the outside surface of the soft magnetic core and is fixed to the soft magnetic core. The direction of the areas formed as strips of the hard magnetic material is substantially perpendicular to the axial direction of the coil conductor.
