Abrégé

A vibration-damping device (10) is a liquid-enclosed vibration-damping device and includes: a tubular first mounting member (11) connected to one of a vibration generator and a vibration absorber, and a second mounting member (12) connected to the other; an elastic body (13) elastically connecting the mounting members; and a partition member (16) partitioning a liquid chamber (19) in the first mounting member (11) within which a liquid (L) is enclosed into a primary liquid chamber (14) that uses the elastic body (13) as a part of a wall surface thereof and a secondary liquid chamber (15), wherein the partition member (16) is formed with a restriction passage (24) communicating the primary and secondary liquid chambers (14, 15) with each other, and a porous body (28) having numerous pores (31), which are disposed in parallel so as to communicate a side of the primary liquid chamber (14) and a side of the secondary liquid chamber (15) with each other, is arranged in the restriction passage (24).
