COIL

PROBLEM TO BE SOLVED: To achieve a coil that is easy to ensure electrical insulation.SOLUTION: A phase coil 21 is formed by using a first coil group constructed by arranging a plurality of segment conductors respectively configured to dispose a conductor crossover part 54 on a first axial direction L1, and a second coil group constructed by arranging a plurality of segment conductors respectively configured to dispose the conductor crossover part 54 on a second axial direction L2. The segment conductors of the first coil group are arranged so that conductor side parts 50 closer to a first circumferential direction C1 are arranged to overlap in a first radial direction with respect to the conductor side parts 50 of the segment conductors in a second circumferential direction C2 of the segment conductors adjacent to each other in the first circumferential direction C1. The segment conductors of the second coil group are arranged so that the conductor side parts 50 in the first circumferential direction C1 are arranged to overlap in a second radial direction with respect to the conductor side parts 50 in the second circumferential direction C2 of the segment conductors adjacent to each other in the first circumferential direction C1. A slot configured to arrange the first coil group therein and a slot configured to arrange the second coil group therein are disposed at positions different from each other by one slot pitch.
