The invention provides a fluid-filled active engine mount which can maintain the low vibration isolation performance of a throttling path, at the same time, obtaining a full and stable low movement spring type isolation effect to middle-high frequency vibration with the frequency approximate to that of the throttling path based on the pressure control of the compressed chamber.In an active fluid-filled engine mount, an oscillation member is excited and displaced by an electromagnetic actuator, and thereby pressure in a pressure receiving chamber is actively controlled. A short circuit passageis provided connecting the pressure receiving chamber and an equilibrium chamber. A ratio of a passage cross-sectional area and a passage length of the short circuit passage (a/l) is provided greaterthan a ratio of a passage cross-sectional area and a passage length of the first orifice passage (A/L) (A/L
