Claim 0:
1. A method for manufacturing a stator including
a stator core including a plurality of slots,
a plurality of coils each including
a pair of slot-housed portions housed in the slots, and
a coil end portion connected to the pair of slot-housed portions and protruded from an end face of the stator core in a central axis direction of the stator core, and

an insulating sheet,
the method comprising:
an insulating sheet preparing step involving preparing the insulating sheet including a plurality of folded portions extending in the central axis direction;
an insulating sheet placing step involving, after the insulating sheet preparing step, placing the insulating sheet in the slots of the stator core;
a first slot-housed portion placing step involving placing a first slot-housed portion of each pair of the slot-housed portions in a first slot included in the slots; and
a second slot-housed portion placing step involving, simultaneously with or after the first slot-housed portion placing step, moving a second slot-housed portion of each pair of the slot-housed portions radially outward while unfolding the insulating sheet in a radially outward direction, intersecting a direction of extension of the folded portions of the insulating sheet, thus placing each second slot-housed portion in a second slot included in the slots and different from the first slot.
