PROBLEM TO BE SOLVED: To provide a liquid-sealed vibration control device capable of sufficiently lowering noise. SOLUTION: This liquid-sealed vibration control device comprises a first mounting device 1, a second mounting device 2, a vibration control base body 3, a diaphragm 9, a partition body 12, and an orifice 25. The partition body 12 comprises an elastic partition membrane 15 and a pair of lattice members 17 and 18. Rib groups 50 are projectedly formed on both surfaces of the elastic partition membrane 15. Each of the rib groups 50 comprises a plurality of first ribs 51 and a plurality of second ribs 52 mixed with each other. The height dimension of the first ribs 51 is set so that their top parts can be positioned apart from lattice members 17 and 18. The height dimension of the second ribs 52 is set so that their top parts can be brought into contact with the lattice members 17 and 18, and the width of the ribs is set to be smaller than that of the first ribs.
