In this rotating electrical machine, each of a first concentric coil, a second concentric coil, a third concentric coil, and a fourth concentric coil has one-side concentric coils whose coil centers are each located on one side in the circumferential direction with respect to a magnetic pole, and other-side concentric coils whose coil centers are each located on the other side in the circumferential direction with respect to a magnetic pole.
