An electric suspension device, includes: an electromagnetic actuator which is arranged in parallel to a spring member provided between a body and a wheel of a vehicle and produces a drive force concerning damping operation and expansion-contraction operation; an information acquisition section which acquires roll velocity of the vehicle; a damping force calculation section which calculates a target damping force as a target value for the damping operation of the electromagnetic actuator; and an ECU which performs drive control for the electromagnetic actuator using a target drive force based on the calculated target damping force. The damping force calculation section calculates a standard damping force of the electromagnetic actuator as a standard value, calculates a supplementary damping force which supplements the standard damping force based on the roll velocity acquired by the information acquisition section, and adds the calculated standard and supplementary damping forces to calculate the target damping force.
