Patent attributes
An edgewise coil which includes a non-circular cross-sectional shaped conductor having a cross-sectional shape defined by a pair of first and second long sides and a pair of first and second short sides, the shaped conductor wire being laminated while being bended with using the first short side as a bending fulcrum so as to form a plurality of laminated wire layers having a rectangular shape in a plan view, wherein the pair of long sides include, in a longitudinal cross section in a pre-bending-process state before the shaped conductor wire is bended, a pair of straight-line regions extending from both ends of the second sides so as to be parallel to each other and a pair of tapered regions extending between the straight-line regions and the first short side, and the pair of tapered regions, in a longitudinal cross section in the pre-bending-process state, come closer to each other as they approach the first short side.
