PROBLEM TO BE SOLVED: To provide a magnetic body that can be manufactured without performing any post-treatment such as adhesion, etc., upon production of magnetic circuit and a hybrid magnetic material obtained by combining a permanent magnet and a soft magnetic material. SOLUTION: A permanent magnet alloy, a soft magnetic material and a metal or alloy required to impact functions such as an electromagnetic shield characteristic, mechanical strength, corrosion resistance, etc., are melted and integrally laminated in a required laminating order by using a rotating roll by the melt extraction method. Then, a diffusion thermal treatment is performed so as to obtain a thin-plate like hybrid magnetic material that has high strength and can be used as a magnetic circuit as it is without using an adhesive. |
