PROBLEM TO BE SOLVED: To provide a liquid sealed vibration control device enabling a sufficient reduction in noise. SOLUTION: This liquid sealed vibration control device comprises a first mounting device, a second mounting device, a vibration control base body, a diaphragm, a partition body, and an orifice. The partition body comprises an elastic partition film 15, a first lattice member, an a second lattice member, and groups of ribs 50 are projectedly formed on both surfaces of the elastic partition film 15. These groups of ribs 50 comprise a plurality of annular first ribs 51A, 51B, 51C, and 51D positioned concentrically to the axis O of the elastic partition film 15 and a plurality of long and short second ribs 52A and 52B positioned radially relative to the axis O, and the plurality of long second ribs 52A and short second ribs 52B are disposed distributedly around the axis O and through the all the periphery of the elastic partition film 15.
