A solenoid driving device with excellent electric power efficiency which drives and controls an actuator including a solenoid and an active vibration damping support device with excellent electric power efficiency which includes the solenoid driving device are disclosed. The solenoid driving device includes a booster circuit 120 which boosts a battery voltage, and driving circuits 121A, 121B which an actuator with the electric power supplied and boosted by the booster circuit 120. ACM_ECU200A including a micro computer 200b calculates the magnitude of the vibration of the engine, an engine vibration cycle and a phase lag to obtain the drive frequency fDV of the actuator in the vibration state estimating unit 234 and the phase detecting unit 235. A booster circuit controlling unit 237 of the micro computer 200b determines the target voltage V based on the drive frequency fDV. The target voltage V is input to the booster circuit 120, and the booster circuit 120 supplies the required electric power to the driving circuits 121A, 121B at the target voltage V*.
