Abstract
A rotating electrical machine includes a rotor and a stator including an annular stator core formed by helically stacking a plurality of core pieces that are connected to each other by connecting portions, the rotor being disposed inside an inner periphery of the stator core. The connecting portions are linearly arranged along a stacking direction of the stator core so that grooves that extend in the stacking direction of the stator core are formed in an outer peripheral surface of the stator core at positions where the connecting portions are provided.
