An electromagnetic suspension device includes: an electromagnetic actuator that generates a driving force related to vibration damping of a vehicle body by an electric motor; a rotational angle acquisition unit that acquires a rotational angle of the electric motor; a rotational angle acceleration calculation unit that calculates a rotational angle acceleration of the electric motor based on the rotational angle; ECU that performs driving force control including inertia compensation control of the electromagnetic actuator based on the rotational angle acceleration; and a relative speed calculation unit that acquires a relative speed between above- and below-spring members. In an area in which a relative speed exceeds a predetermined relative speed threshold, the ECU corrects an amount of inertia compensation so that the amount of inertia compensation is decreased, as compared with an area in which a relative speed value is the relative speed threshold or less.
