1. A cooling device comprising:
- a coolant jetting member that is attached to a power transmitting device, wherein the power transmitting device performs wireless power supply to a movable power receiving device using a first coil; and
a plurality of coolant jet ports formed in the coolant jetting member that spray a liquid coolant on a second coil provided on the power receiving device only when an amount of heat generated by the second coil exceeds a threshold;
wherein at least a part of the coolant jetting member is provided in a facing region where the first coil and the second coil face each other during the wireless power supply.
