In order to provide a damping control device for an electric vehicle, a device enabling damping control corresponding to an accurate determination of the presence or absence of a change in transmission ratio in the present invention provides a damping control device for an electric vehicle, the device being characterized by being provided with a drive system, which has a continuously variable transmission (CVT) between a motor (MG) and left and right front wheels (FL and FR), a feedback control unit (32), which suppresses a vibration accompanying a disturbance in the rotational speed of the motor (MG), and an operation determination unit (301), which determines whether or not an absolute value of a second-order differential of the transmission ratio is equal to, or greater than, a predetermined value, wherein when the absolute value of the second-order differential of the transmission ratio is equal to, or greater than, the predetermined value, the feedback control unit (32) performs control of the output torque of the motor (MG) whereby a compensation torque component for suppressing a vibration accompanying a gear shift is subtracted from a compensation torque (Tm (F/B)).
