Abstract
A stator of a rotating electric machine Includes a stator core that has a plurality of slots and in which electromagnetic steel sheets are stacked in the axial direction, a stator coil inserted into the slots, a finger plate provided on an axially outer end surface of the stator core, and a clamper provided on an axially outer end surface of the finger plate and for clamping the stator core via the finger plate. Furthermore, a rectangular parallelepiped-shaped notch is provided on a part of the finger plate from any position at an anti-stator core side located lateral to an upper stator coil in a circumferential direction to a radially inner end portion.
