An electric vehicle comprises a driving motor which generates heat during an operation of the driving motor; a driving power transmission mechanism which transmits driving power of the driving motor to a rear wheel (drive wheel); an oil pan (first reservoir section) which is placed below the driving motor and reserves oil (coolant) therein; an oil reservoir (second reservoir section) which is placed above the driving motor and reserves the oil (coolant) therein; a fluid passage which causes the oil pan and the oil reservoir to be in communication with each other; and a pump which supplies the oil (coolant) from the oil pan to the oil reservoir through the fluid passage, and the oil reservoir includes a first drop hole through which the oil (coolant) is dropped toward the driving motor by a gravitational force.
