A vehicle to be driven by electric power which is wirelessly transmitted from a power transmitter having two transmission electrodes includes: two reception electrodes to receive AC power from the two transmission electrodes through capacitive coupling respectively with the two transmission electrodes; a power receiving circuit which is connected to the two reception electrodes to convert AC power received by the two reception electrodes into DC power or another form of AC power, and supply the DC power or other form of AC power to an electric motor which drives the vehicle; and a control circuit which, while the vehicle is traveling over the two transmission electrodes, determines not to receive electric power from the power transmitter when a value of at least one of power, voltage and current in the power receiving circuit, or a change rate over time thereof, exceeds a threshold value.
