PROBLEM TO BE SOLVED: To provide a liquid-sealed vibration control device capable of sufficiently absorbing liquid pressure of a first liquid chamber at input of high frequency vibration and reducing the manufacturing cost. SOLUTION: The liquid-sealed vibration control device is equipped with a first mounting tool 1, a second mounting tool 2, a vibration control base body 3, a diaphragm 9, a partitioning body 12, and an orifice 25. The partitioning body 12 comprises the orifice forming body 16 and an elastic partitioning film 15, and the orifice forming body 16 is composed of a first orifice forming member 17 and a second orifice forming member 18. A first pinching part 4 and a second pinching part 5 are provided for pinching a pinched part 46 constituted of an expansion part 41 of the elastic partitioning film 15 and an elastic partitioning film part 45 in the core direction G of the orifice forming body 16. A clearance is not formed even at the time of vibration input between a pinched surface 45M1 of the elastic partitioning film part 45 and a first pinching surface 51 of the first pinching part 4, and between a second pinched surface 45M2 of the elastic partitioning film part 45 and a second pinching surface 62 of the second pinching part 5.
