摘要： [Problem] When a core is configured by injection-molding a mixture including a soft magnetic powder and a thermoplastic resin and a reactor is manufactured by integrating a coil in a state where the coil is embedded in the inner portion of core, positional misalignment or deformation of coil at the time of molding the core can be effectively prevented, and the core can be favorably molded using an injection molding method.[Solution Means] A reactor 15 is manufactured through a step A of encasing a coil 10 configured by winding a wire in a state where an insulating layer is interposed between the wires with an electrically insulating resin to mold an encased coil body 24, and a step of molding a core 16 by injection-molding a mixture including a soft magnetic powder and a thermoplastic resin in a state where the encased coil body 24 is enclosed. In addition, the injection molding of the core 16 is performed so as to be divided into a step in which a primary molded body 16-1 having a container shape alone is molded and a step in which a secondary molded body 16-2 is molded in a state where the encased coil body 24 is set along with the primary molded body 16-1.
