A liquid-sealed antivibration device is equipped with a shaft member and a sleeve member, an antivibration base body constituted by a rubber-like elastic body which elastically supports the sleeve member relative to the shaft member and which defines a first liquid chamber and a second liquid chamber between the shaft member and the sleeve member, and an orifice forming member made of a synthetic resin and disposed inside the sleeve member. The orifice forming member is formed with end surfaces on which a hole portion piercing along the axis of the shaft member opens, and an outer peripheral surface adhered closely to the sleeve member to form a groove portion becoming an orifice which makes the first liquid chamber communicate with the second liquid chamber, and recesses formed at corner portions defined by the end surfaces and the outer peripheral surface are connected to the hole portion.
