1. A stator comprising:
a plurality of split cores each having a yoke and a tooth, the plurality of split cores being connected such that the yoke of each one split core together form an annular shape in a state where each side surface of each tooth is covered with an insulating sheet and a coil is wound around each tooth,
wherein the insulating sheet is one of a first insulating sheet and a second insulating sheet, the first insulating sheet and the second insulating sheet are respectively located in each slot partitioned by each two teeth adjacent to each other among the plurality of split cores,
the first insulating sheet is located between the side surface of one of the two adjacent teeth and the coil wound around the tooth, and is located between the coils respectively wound around the two adjacent teeth in each slot, and
the second insulating sheet is located between the side surface of another one of the two adjacent teeth and the coil wound around the tooth, and is not located between the coils respectively wound around the two adjacent teeth in each slot.
