In a liquid-sealed antivibration device 10 which includes: a main liquid chamber 34A where a vibration-isolating base 16 forms a portion of a chamber wall thereof; a subsidiary liquid chamber 34B where a diaphragm 36 forms a portion of a chamber wall thereof; a partition element 38 by which the main liquid chamber 34A and the subsidiary liquid chamber 34A are partitioned from each other, and an orifice flow passage 40 which allows the main liquid chamber 34A and the subsidiary liquid chamber 34B to be communicated with each other, an elastic membrane 42 is formed on the partition element 38, and the elastic membrane 42 is formed of rubber composition containing butyl rubber or halogenated butyl rubber. Due to such a constitution, an abnormal sound generated by collision of the elastic membrane 42 is reduced.
