PROBLEM TO BE SOLVED: To exert a stable vibration control characteristic by restraining variation of a distance between a pair of partition plates, and to improve assemblability. SOLUTION: This liquid-sealed vibration control device 10 is provided with a first mounting means 12, a second mounting means 14, a vibration control base body 16, a diaphragm 29, a partition body 30, and an orifice 32. The partition body is composed of an annular orifice formation member 34, a rubber wall 36 closing a space of its inside surface 34A, and a pair of partition plates 38 and 40 sandwiching the rubber wall in the axis direction X, and the pair of partition plates are connected through a connection part 50 penetrating the rubber wall 36. The connection part 50 comprises a first fitting part 52 of the one-side partition plate 38 and a second fitting part 54 of the other-side partition plate 40, and is composed by slidably fitting both the fitting parts to each other in a first direction Y orthogonal to the axis direction X. The rubber wall 36 is integrally vulcanized and molded between the pair of partition plates 38 and 40 thus previously connected to each other, and the orifice formation member 34.
