Abstract
A rotating electrical machine includes a stator including at least two element coils of the same phase each having a plurality of turns and connected to each other through a coil-to-coil connection wire, the element coils being arranged in adjacent slots, respectively; and a rotor rotatably provided to the stator through a gap. The element coils of the same phase are fitted in the adjacent slots so that wound around portions of the element coils partially overlap each other. The coil-to-coil connection wire connects at a coil end portion conductor wires extending from linear conductor wire portions of innermost wires of the element coils contained in the slots.
