PROBLEM TO BE SOLVED: To provide a fluid-filled vibration isolator of a novel structure capable exercising a vibration isolating effect superior with respect to any vibration of a plurality of different frequency ranges without using an actuator needing supply of external energy. SOLUTION: The fluid-filled vibration isolator is provided with a one-way valve 70 allowing only a fluid flow from a fluid chamber 134 to an intermediate chamber 138, and a hole 90 for static pressure recovery communicating the pressure chamber 134 and the intermediate chamber 138, allowing only a fluid flow amount insufficient for recovering capacity increase of the intermediate chamber 138 following the fluid flow through the one-way valve 70 in an input state of tuning vibration of an orifice passage 142 communicating the pressure chamber 134 with an equilibration chamber 136, and allowing a fluid flow sufficient for recovering the initial capacity of the intermediate chamber 138 in a non-input state of the tuning vibration of the orifice passage 142.
