Provided is an electric motorcycle including a traveling motor, 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 and a circuit board of the inverter. A radiator is disposed outside cases of a power plant and a power control controller so as to allow a traveling wind to pass by. Cooling oil is circulated between the radiator and a case of at least one of the power plant and power control controller. 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.
