Abstract
[Problem] Provided is an injection-molded reactor which has excellent heat dissipation properties and in which the internal temperature of the core can be satisfactorily inhibited from rising due to heat generation when the reactor is in operation. [Solution Means] A material for a core obtained by mixing a soft magnetic powder, a resin binder, and a thermally conductive fibrous filler having a higher thermal conductivity than the soft magnetic powder in accordance with X·(soft magnetic powder)+Y·(thermally conductive filler)+(100-X-Y)·(resin binder), wherein X, indicating the proportion of the soft magnetic powder, is 83 to 96% by mass and Y, indicating the proportion of the thermally conductive filler, is 0.2 to 6.8% by mass, is used to mold a coreso that a coilobtained by winding an electric wire is embedded therein without an interval, thereby configuring a reactor
