<p>In order to obtain a reactor that is capable of reducing the eddy-current loss at a winding wire caused by means of the leakage flux from the gap of an iron core, the reactor is provided with: iron cores (11, 12) which have at least one pair of leg portions (14p, 14q) facing one another and which are formed with a gap (13) by means of the pair of leg portions (14p, 14q); and winding wires (1, 2) which are wound around the pair of leg portions (14p, 14q) along the direction in which the pair of leg portions (14p, 14q) extend and which are multiply wound so as to overlap with one another in a direction that is roughly perpendicular to the aforementioned direction in which the pair of leg portions (14p, 14q) extend. In a region surrounding the gap, the innermost turn of the winding wires (1, 2) is constituted by a litz wire (1) in which multiple wires are twisted together, and the outermost turn of the winding wires (1, 2) is constituted by a single wire (2).</p> |
