Rotary electric machine, rotary electric machine stator, and rotary electric machine stator manufacturing method

The present invention provides a rotary electric machine, a rotary electric machine stator, and a rotary electric machine stator manufacturing method that can prevent reductions in stator coil space factor, and that enable a temperature sensor to be placed in contact with a stator coil more reliably. An insulator (23) includes: a trunk portion (231) that is interposed between a tooth and a stator coil (22); and a first flange portion (232) that is disposed on the trunk portion so as to be adjacent to the stator coil in a radial direction of a stator core (21). A notch portion (234) is disposed on a flange protruding portion (232a) of the first flange portion that protrudes from the stator core in the axial direction of the stator core from an outer circumferential portion of the flange protruding portion toward the trunk portion. A holder (25) that has a holder main body (251) that is disposed on the notch portion is mounted onto the flange protruding portion. A temperature sensor (24) is held between the holder main body (251) and the stator coil (22).
