An electric vehicle, such as an electric two-wheeled vehicle (1), is provided with: a main oil path (68) connected to an oil supply source in order to supply lubricating oil to a travel motor (30) and a power transmitting mechanism (such as a transmission (40)) for transmitting the output of the travel motor (30) to a wheel (3); a first oil path, such as a lower hose (71), for leading the oil to an oil cooler (28) from the main oil path (68); and a second oil path, such as a transmission-side oil path (73), branched from the main oil path (68) and supplying the oil to at least the power transmitting mechanism. The oil can be appropriately supplied to portions to be lubricated of the travel drive system of the vehicle and to portions to be cooled, such as the travel motor (30) and an inverter (27), in response to a request from each of the portions, and in addition, the capacity of the oil cooler (28) can be made small.
