摘要： A method of manufacturing a magnetic body in which insulating magnetic powder particles are stacked and press-molded in a molding space, and wiring is formed on a surface of the insulating magnetic powder particles solidified by press molding is provided according to the present invention. The method includes: a first step S10 of preparing a wiring plate which includes a sheet-shaped base plate and the wiring which is formed on the base plate and is removable from the base plate; a second step S20 of stacking the insulating magnetic powder particles in the molding space, arranging the wiring plate on a surface of the insulating magnetic powder particles in a state that the wiring faces the surface of the insulating magnetic powder particles in an opposed manner, and press-molding the insulating magnetic powder particles and the wiring plate; and a third step S30 of removing the base plate from the surface of the solidified insulating magnetic powder particles while leaving the wiring on the insulating magnetic powder particles in this order. According to the method of manufacturing a magnetic body of the present invention, it is possible to prevent the corrosion of the insulating magnetic powder particles thus realizing the manufacture of a highly reliable magnetic body.
