The purpose of the present invention is to obtain a rotary electric machine capable of reducing an amount of leakage magnetic flux passing through a connection section. A cutout part is formed on each connection section on the side where a magnetic gap section is provided. The connection section has a slot-side thinned connection part positioned closer to the side where a slot section is provided than to the cutout part, and slot protrusion parts, which protrude from the slot section toward the magnetic gap section side beyond the slot-side thinned connection part, are formed at parts of the connection section which are displaced in the circumferential direction of the connection section with respect to the part where the slot-side thinned connection part is formed, whereby the slot protrusion parts are disposed on both sides of the cutout part in the circumferential direction.
