Abstract
An assembly conductor manufacturing method includes aligning, around a center strand, a plurality of peripheral strands, each having at least two side surfaces, one of which opposes an adjacent peripheral strand on one side in a circumferential direction and the other of which opposes an adjacent peripheral strand on the other side in the circumferential direction, so as to form an assembly conductor in which the center strand and the peripheral strands are aligned; twisting the plurality of peripheral strands around the center strand that forms the assembly conductor; and plastic forming the twisted assembly conductor into a substantially rectangular sectional shape. The peripheral strand provided with the two side surfaces has a sectional shape in which a width between the side surfaces becomes narrower toward the center strand.
