A vibration isolator includes a partition member (15) that partitions a liquid chamber (16) in a first mounting member (11) into a primary liquid chamber (16a) using an 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 or secondary liquid chamber (16a or 16b) toward the inside of the partition member and are open toward the movable member (23). The partition member (15) is equipped with partition plate parts (18 and 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 and dividing the housing chamber from secondary liquid chamber (16a or 16b). The communicating holes (22) include communicating pores (24) which pass through the partition plate parts (18 and 19), and each of which has an inner diameter of 3.6 mm or less.
