To provide an electric power suspension device that can improve a response to a harshness so as to generate no response lag.SOLUTION: An electric power suspension device 11 comprises: a harshness input extraction part 43a which extracts harshness input from a road surface input signal; an attenuation force computation part 43b which computes attenuation force of a shock absorber on the basis of the harshness input; and a load control part 45 which controls the attenuation force of the shock absorber on the basis of a computation result of the attenuation force computation part before the vehicle passes a harshness road surface.SELECTED DRAWING: Figure 3
