Patent attributes
A coil includes a series of turns constituted by a first turn to an n-th turn of a conductive wire having a quadrangular cross-section, where the conductive wire is wound in a spiral shape and is stacked in a vertical direction, and n is an integer equal to or greater than 3. In addition, at least a part of the conductive wire of the first turn to the n-th turn is provided with a deformed part whose shape is different from shapes of the other parts. Further, the first turn and the n-th turn are on the both end parts of the series of turns. In addition, at each of the first turn and the n-th turn, the deformed part makes an outer surface positioned on an opposite side with respect to a center of the series of turns extend in a flush manner along a plane intersecting the series of turns.
