A vibration isolator includes: a first mounting member (11) and a second mounting member (12); an elastic body (13) connecting the mounting members; a partition member (15) partitioning a liquid chamber (16) in the first mounting member (11) into a primary liquid chamber (16a) using the elastic body (13) as a part of a wall surface thereof and a secondary liquid chamber (16b); and a movable member (23) housed in a housing chamber (20) provided within the partition member (15), the movable member being free to be deformed or displaced in an axial direction of the first mounting member (11). The partition member (15) is provided with a plurality of communicating holes (22) that extend from a portion of the partition member (15) which is exposed to the primary liquid chamber (16a) or the secondary liquid chamber (16b) toward an inside of the partition member and are opened toward the movable member (23). The partition member (15) is equipped with partition plate parts (18, 19) of which front and back surfaces are directed in the axial direction of the first mounting member, the partition plate parts dividing the housing chamber (20) from the primary liquid chamber (16a) and dividing the housing chamber from the secondary liquid chamber (16b), and the partition plate parts bulging outward. The communicating holes (22) pass through the partition plate parts (18, 19) in the axial direction.
