To provide an active fluid-sealed vibration control device having a novel structure capable of exerting vibration control effect effectively by driving and displacing a vibration plate stably.

The vibration plate 100 is elastically supported to a second mounting member 14 by first and second vibration plate support plate springs 120, 128 positioned on both sides sandwiching the vibration plate 100 in the axial direction of drive shafts 102, 108 in the vibration plate 100 of a mounting main body 18, and expanding in a direction orthogonal to the axial direction respectively. An electromagnetic actuator 20 formed separately from the mounting main body 18 is positioned on both sides sandwiching a mover 152 in an axial direction of output shafts 180, 184 of the electromagnetic actuator 20 so as to elastically support the mover 152 to housings 164, 166 by first and second mover support plate springs 190, 202 expanding in the direction orthogonal to the axial direction respectively, holding the drive shafts 102, 108 and the output shafts 180, 184 in a contact state with by pressing each other in the axial direction.
