<p>PROBLEM TO BE SOLVED: To provide a technique to reduce a copper loss while preventing dispersion among a plurality of element wires.SOLUTION: A twisted aggregated conductor wire 31 (an aggregated conductor) formed by intertwining a plurality of element wires 20 coated with an insulation layer includes a straight line part 12 extending linearly and a bending part 15 that is being bent. The intertwining pitch of the straight line part 12 is larger than the intertwining pitch of the bending part 15. In this manner, at the bending part 15 where a dispersion among the plurality of element wires 20 becomes a problem, by intertwining the plurality of element wires 20 strongly, the dispersion among the plurality of element wires 20 at the bending part 15 is effectively prevented, while at the straight line part 12 where the dispersion among the plurality of element wires 20 does not become a problem, by intertwining the plurality of element wires 20 relatively weakly, the length of each element wire 20 at the straight line part 12 becomes short so that a copper loss of the twisted aggregated conductor wire 31 at the straight line part 12 can be suppressed.</p> |
