Claim:
1. An electric rotating machine comprising: a rotor mounted on a rotating shaft rotatably supported; and a stator disposed around an outer circumference of the rotor via a minute clearance between the rotor and the stator; the stator including a stator core having a plurality of slots formed in a circumferential direction, a stator winding formed by connecting a plurality of segment conductors inserted into the slots of the stator core, and a thermistor for measuring the temperature of the stator winding, and the stator winding including slot portions received in the slots, and connecting portions each of which connects end portions of the slot portions, wherein a temperature measuring element portion of the thermistor is fitted in a minute gap defined by the connecting portions of the segment conductors at a stator coil end, the stator coil end being formed by arranging a plurality of the segment conductors in the slots of the stator core to thereby form the connecting portions of the segment conductors at the end portion of the stator core, and the thermistor is separated from the connecting portions of the segment conductors only by dead air that defines the minute gap, wherein the minute gap is defined by at least four connecting portions of the segment conductors that immediately surround the temperature measuring element portion of the thermistor.
