To provide an active liquid-sealed vibration control device excellent in fixing workability of a movable element of an actuator and a vibration plate and to solve the problem that movement of the movable element is inhibited.
The active liquid-sealed vibration control device comprises a first mounting tool 10, a second mounting tool 12, a vibration control base body 14 composed of a rubber elastic body connecting the mounting tools 10, 12, a first liquid chamber 16 having the vibration control base body 14 as a part of a chamber wall, a vibration plate 24 as another part of the chamber wall of the first liquid chamber 16, and the actuator 26 for driving the vibration of the vibration plate 24. The actuator 26 consists of a stator 54 fixed to the side of the second mounting tool 12, and the movable element 56 reciprocatingly supported with respect to the stator 54 and connected to the vibration plate 24 for driving the vibration thereof. A tip end 56a of the movable element 56 is adsorbed and fixed to the vibration plate 24 by a magnet 74.
