Claim Text:
1. A reactor comprising: a plurality of coils obtained by winding a winding wire; and a core that magnetically couples the plurality of coils to each other, wherein the plurality of coils are arranged parallel to each other such that adjacent outer circumferential surfaces of the plurality of coils are opposed to each other, ends of each of the coils on one side are electrically connected to each other, and the plurality of coils are electrically connected in parallel, wherein the core comprises: a coupling coefficient adjuster that adjusts a coupling coefficient between adjacent coils, wherein the coupling coefficient adjuster is disposed between the adjacent coils, wherein the coupling coefficient adjuster comprises a shielding plate, wherein a thickness of the coupling coefficient adjuster is between one and two times a coil skin depth, and wherein the shielding plate is provided at positions corresponding to the gap materials in the magnetic leg portions.
