An electric motor includes a housing, a stator, and a rotor. The stator is composed of a stator core and a stator coil. The stator coil is composed of a plurality of individual coils provided to teeth of the stator core. The housing has lubricating oil supply portion, through which the lubricating oil is supplied onto coil ends of upper individual coils. A temperature detector for detecting the temperature of the stator coil is disposed at a position lower than an axis of a rotor and higher than an oil level of the lubricating oil accumulated in the bottom portion of the housing.
