The method of manufacturing a bus, bus and module bus

Bus (1) comprising: the laminated conductor lines (20), the plate-shaped first conductor line (21) of the second line conductor (22) and plate-like and arranged in the longitudinal direction, folded in both the first conductor line (21) and a second conductor wire (22) on the outer surface of each of widthwise opposite; and a terminal portion (30), the laminated conductor lines (20) and both end sides of the first conductor line (21) and a second conductor wire (22) engages, wherein the first plate-shaped conductor wire (21) the strip conductor (11, 12) in the width direction of the adjacent spirally wound, and the opposite inside phase near the surface, the second plate-shaped conductor wire (22) the strip conductor (11, 12) spirally wound in a direction opposite to the first conductor line (21) and the opposite surface of the inner phase near .
