摘要：<P>PROBLEM TO BE SOLVED: To provide a manufacturing method or the like for a laminated soft magnetic member which shows superior permeability in a high frequency band despite having a thin body. <P>SOLUTION: Soft magnetic sheets 1, 11 are laminated via insulating layers to form the laminated soft magnetic member 5 in which the insulating layers and soft magnetic metal layers are laminated alternately. Before laminating the soft magnetic sheets 1, 11, or after laminating them and making the laminated soft magnetic member 5, heat treatment is carried out under the conditions that are set in accordance with a purpose of the treatment or the like. The heat treatment may be executed in combination with a pressure application treatment. <P>COPYRIGHT: (C)2005,JPO&NCIPI
