A reactor includes a coil having gaps between adjacent turns of a winding, a core inserted through the coil, and a heat-dissipating material that is in contact with a side face of the coil. The heat-dissipating material is inserted between the adjacent turns of the winding of the coil, and the thickness of the heat-dissipating material outside the coil in a direction of an axis of the coil is smaller than the thickness of the heat-dissipating material between the adjacent turns of the winding. By reducing the thickness of the heat-dissipating material outside the coil where contribution to coil cooling is small, the amount of the heat-dissipating material can be reduced without lowering the cooling performance to the coil.
