Alignment method and alignment device

An alignment method of an electrical conductor in which a plurality of substantially U-shaped electrical conductors are overlapped and are aligned in an annular shape, the method comprising:

• an arranging step of disposing the electrical conductors in an annular shape at intervals at which the electrical conductors do not overlap in a circumferential direction of the annular shape by causing a plurality of gripping devices disposed in the annular shape to each grip one end portions of the electrical conductors;
• and
• an aligning step of aligning the plurality of electrical conductors in the annular shape while overlapping the electrical conductors in a circumferential direction of the annular shape by moving the gripping devices in a radially inward direction of the annular shape,
• wherein the gripping device has a pair of claws capable of pinching one leg portions of the substantially U-shaped electrical conductors one by one, one claw has a length capable of gripping one leg portion, and the other claw has a length capable of gripping one leg portion of one substantially U-shaped electrical conductor and gripping the other leg portion of the other substantially U-shaped electrical conductor.
