Provided is an electric rotating machine that is improved in the temperature detection accuracy of a thermistor and in ability to follow up a sudden change in the temperature of a stator winding. An electric rotating machine 100 includes a rotor 50 mounted on a rotating shaft rotatably supported and a stator 30 disposed around the outer circumference of the rotor via a minute clearance between the rotor and the stator. The stator 30 includes a stator core 32 having a plurality of slots formed in a circumferential direction, a stator winding 34 which connects a plurality of segment conductors inserted into the slots of the stator core, and a thermistor 38 which measures the temperature of the stator winding. The stator winding 34 has slot portions 21 received in the slots and connecting portions 23 each of which connects the end portions of the slot portions. A temperature measuring element portion 1 of the thermistor 38 is received in a minute gap sandwiched between the connecting portions of the segment conductors at a stator coil end.
