A vibration-damping device comprising: a tubular first attachment member coupled to any one of a vibration generating part and a vibration receiving part, and a second attachment member coupled to the other thereof; an elastic body coupling both of the attachment members (11, 12); and a partitioning member that partitions a liquid chamber within the first attachment member having a liquid enclosed therein into a first liquid chamber and a second liquid chamber, wherein at least any one of the first liquid chamber and the second liquid chamber has the elastic body on a portion of a wall surface thereof, wherein the partitioning member is provided with a communication chamber that allows the first liquid chamber and the second liquid chamber to communicate with each other, wherein a first wall surface and a second wall surface that face each other with the communication chamber disposed therebetween among wall surfaces that form the communication chamber in the partitioning member are separately provided with communication holes (31, 32) that open toward the communication chamber, characterized in that a plurality of first communication holes that are provided in the first wall surface and allow the communication chamber and the first liquid chamber to communicate with each other, and a plurality of second communication holes that are provided in the second wall surface and allow the communication chamber and the second liquid chamber to communicate with each other are provided as the communication holes (31, 32), wherein the first communication holes and the second communication holes are arranged to be offset from each other in an orthogonal direction orthogonal to a facing direction in which the first wall surface and the second wall surface face each other, and wherein the first communication holes are formed by the inside of first protruding tubes that protrude into the communication chamber from the first wall surface. a tubular first attachment member coupled to any one of a vibration generating part and a vibration receiving part, and a second attachment member coupled to the other thereof; an elastic body coupling both of the attachment members (11, 12); and a partitioning member that partitions a liquid chamber within the first attachment member having a liquid enclosed therein into a first liquid chamber and a second liquid chamber, wherein at least any one of the first liquid chamber and the second liquid chamber has the elastic body on a portion of a wall surface thereof, wherein the partitioning member is provided with a communication chamber that allows the first liquid chamber and the second liquid chamber to communicate with each other, wherein a first wall surface and a second wall surface that face each other with the communication chamber disposed therebetween among wall surfaces that form the communication chamber in the partitioning member are separately provided with communication holes (31, 32) that open toward the communication chamber, characterized in that a plurality of first communication holes that are provided in the first wall surface and allow the communication chamber and the first liquid chamber to communicate with each other, and a plurality of second communication holes that are provided in the second wall surface and allow the communication chamber and the second liquid chamber to communicate with each other are provided as the communication holes (31, 32), wherein the first communication holes and the second communication holes are arranged to be offset from each other in an orthogonal direction orthogonal to a facing direction in which the first wall surface and the second wall surface face each other, and wherein the first communication holes are formed by the inside of first protruding tubes that protrude into the communication chamber from the first wall surface.
