Abstract: A rotary electric machine includes a stator. A plurality of slots are formed in a stator core of the stator, and a coil and an insulating sheet layer are inserted into the slots. A first coil side surface and a second coil side surface of the coil inserted into the slots serve as adhesive regions, which are adhered to a slot inner circumferential surface via the insulating sheet layer. In addition, a first coil end surface and a second coil end surface of the coil inserted into the slots serve as non-adhesive regions, which are maintained in a non-contact manner with respect to the slot inner circumferential surface.
