Provided is an electric motorcycle (1) including a traveling motor (20), and a power supply circuit of an inverter and the like, in which a non-conducting cooling oil is supplied to be brought into direct contact with at least one of an electromagnetic coil of the traveling motor (20) and a circuit board (60a) of the inverter. A radiator (70) is disposed outside cases of a power plant (40) and a power control controller (60) so as to allow a traveling wind to pass by. Cooling oil is circulated between the radiator (70) and a case of at least one of the power plant (40) and power control controller (60). A cooling structure for an electric motor and the like that can obtain a higher cooling efficiency than a conventional art while having a simple structure which hardly causes increases in size, weight, cost, and the like can be provided.
