An electric motor (1) includes a housing (8), a stator (9), and a rotor (10). The stator (9) is composed of a stator core (30) and a stator coil (31). The stator coil (31) is composed of a plurality of individual coils (33) provided to teeth (30b) of the stator core (30). The housing (8) has lubricating oil supply portion (70), (71) through which the lubricating oil is supplied onto coil ends (33a) of upper individual coils (33). A temperature detector (75) for detecting the temperature of the stator coil (31) is disposed at a position lower than an axis (O) of a rotor (10) and higher than an oil level (66) of the lubricating oil accumulated in the bottom portion of the housing (8).
