Abstract
An object of the present invention is to provide a highly efficient and highly reliable rotary electric machine. A rotary electric machine includes: a stator around which a plurality of coils are wound; and a rotor which is supported to be freely rotatable with a predetermined gap with respect to the stator. The coil has at least one connection portion per turn in a slot of the stator. Conductors to be connected mutually have steps at the connection portion, and are fitted with other conductors so as to mutually fill the steps. The steps have contact surfaces that come into contact with each other in the slot to be electrically conducted. A thermally expandable sheet capable of pressurizing the coil in a radial direction of the stator is arranged in the slot.
