A vibration-damping device (10) includes a first attachment member (11), a second attachment member (12), an elastic body (13), and a partitioning member (16). Limiting passages (31, 32) are formed in the partitioning member (16), and the limiting passages (31, 32) include a first limiting passage (31) and a second limiting passage (32). An inner peripheral surface of the first limiting passage (31) is provided with flow changing protrusions (33, 34) that protrude toward an inner side in a radial direction of the first limiting passage (31) and that changes the flow of a liquid (L) that flows through the first limiting passage (31) in an axial direction of the first limiting passage (31). In a vertical cross-sectional view passing through an axis of the first limiting passage (31) and through the flow changing protrusions (33, 34), the first limiting passage (31) and the flow changing protrusion1 (33, 34) have symmetrical shapes with respect to the axis. Protruding ends of the flow changing protrusions (33, 34) form inner peripheral edges of passage holes (33c, 34c) that are open on both sides in the axial direction.
