A straddle electric vehicle comprises a battery case accommodating a battery which is an electric power supply for an electric motor; an inverter which converts DC power stored in the battery into AC power and supplies the AC power to the electric motor; an air passage through which ram air is guided to an interior of a battery case and discharges air from the battery case; and a radiator for cooling a coolant used to cool the inverter using water or oil, wherein the radiator is placed forward relative to an air inlet of the air passage or within the air passage.
