PROBLEM TO BE SOLVED: To provide a vibration control device capable of improving heat durability without being affected by distortion on resin adhered on a core member. SOLUTION: One of rigid members mounted on a vibration generation side and a vibration transmission side is the core member 2 made of a metal member, and the other is a sleeve-like member 3. One end of the sleeve-like member 3 is liquid-tightly connected to an outer peripheral face of the core member 2 by a rubber elastic body 4 surrounding the core member 2, and the other end of the sleeve-like member 3 is liquid-tightly sealed by a diaphragm 6. A liquid chamber 7 defined at least between the diaphragm and the rubber elastic body and sealing liquid is partitioned in two in the axial direction of the sleeve-like member by a partitioning member 8 into a main liquid chamber 7a and a sub liquid chamber 7b. The main liquid chamber 7a is communicated with the sub liquid chamber 7b thereof by a limit passage 9a mainly comprising a rigid member. At least a portion of the core member 2 further on the liquid chamber side than an intermediate part is covered by a resin layer 11, and a tip end portion of the core member 2 on the liquid chamber side is exposed.
