A vibration-damping device (10) of the present invention includes a first attachment member (11), a second attachment member (12), an elastic body (13), and a partition member (16). In the partition member, a restriction passage (24) through which the first liquid chamber (14) and the second liquid chamber (15) communicate with each other is formed. The restriction passage includes a first communicating portion (26) which opens to the first liquid chamber, a second communicating portion (27) which opens to the second liquid chamber, and a main body flow passage (25) through which the first communicating portion and the second communicating portion communicate with each other. At least one of the first communicating portion and the second communicating portion includes a plurality of fine holes (26a) which are disposed in a flow passage direction of the main body flow passage. In plurality of fine holes, a flow passage length of a fine hole located apart from the other of the first communicating portion and the second communicating portion in the flow passage direction becomes longer.
