PROBLEM TO BE SOLVED: To provide a technique for reducing nonuniformity of magnetic flux, in a reactor where a cooler is in contact with a cooler covering the periphery of a coil, and including a heat transfer member penetrating the core and coming into contact with the cooler and the coil.SOLUTION: A reactor 200 includes a core 4 embedding a coil 6, and a cooler 3 in contact with the core 4. Furthermore, the reactor includes a pair of protrusions 3b (heat transfer members) elongated in the direction of the winding axis CL of the coil and penetrating the core 4, and having one end in contact with the cooler 3 and the other end in contact with the coil 6. The pair of protrusions 3b are provided while being distributed to the opposite sides of a plane passing the winding axis CL of the coil 6 and perpendicular to the surface of the cooler 3. The majority of magnetic flux generated in the coil 6 is curved on the outer periphery of the coil so as to avoid the protrusions 3b, but since the protrusions 3b are distributed to the opposite sides of the winding axis CL, nonuniformity of magnetic flux is reduced. |
