Abstract
An electric rotating machine includes a rotor, a stator, and a thermistor. The thermistor has a temperature measuring element portion that is fitted in a minute gap defined by connecting portions of segment conductors at a stator coil end. The stator coil end is formed by arranging a plurality of the segment conductors in slots of a stator core to thereby form connecting portions of the segment conductors at the end portion of the stator core. The thermistor is separated from the connecting portions of the segment conductors only by dead air that defines the minute gap.
