A fluid-filled active damping apparatus having a pressure receiving chamber divided by a partition member into a primary fluid chamber and an auxiliary fluid chamber. The partition member houses a movable plate extending entirely across between opposing faces of upper and lower through holes of the partition member. Elastic projections of the movable plate from its outer peripheral portion are held sandwiched between upper and lower divider plates of the partition member, so that the movable plate is exposed to the primary fluid chamber through the upper through hole and to the auxiliary fluid chamber through the lower through hole. A connecting gap is formed between the upper and lower divider plates and the peripheral portion of the movable plate where the elastic projections have not been formed, to connect the primary and the auxiliary fluid chambers through the through holes and the connecting gap.
