Abstract: A stator of a rotary electric machine includes a stator core and a coil. The stator core includes slots extending in an axial direction of the stator core and a first axial end surface in the axial direction. The coil is attached to the stator core and includes slot coils disposed in the slots and connection coils. At least one of the slot coils includes a slit in a part positioned in a slot among the slots. The slit extends through the at least one of the slot coils from a first axial end side of the stator core toward a second axial end side of the stator core opposite to the first axial end side in the axial direction. The connection coils are connected to the slot coils at a contact portion at a position outward from the first axial end surface in the axial direction.
