The invention relates to a stopper, comprising a remote end, a near end and an elastic weaving body arranged between the remote end and the near end and waved by meshes. The elastic weaving body is waved by multi-step rayon meshes which at least comprise a first-step rayon mesh arranged most closely to the remote end and waved by a plurality of first-step meshes and a second-step rayon mesh waved by a plurality of first-step meshes and a plurality of second-step meshes. The minimal cross section of the first-step rayon mesh after being compressed towards a direction vertical to the axial direction of the elastic weaving body is smaller than the minimal cross section of any other-step rayon mesh after being compressed towards the axial direction. The invention also relates to a method for manufacturing the stopper. Because of the use of multi-step rayon meshes, the stopper does not need a permanent plug, thereby not only reducing the risk of the damage of a metal plug to the human body, but also well avoiding the stacked meshes when the remote end of the traditional stopper without a plug is withdrawn and put back to the scabbard, and greatly reducing the sheathing resistance. In addition, the stopper is suitable for smaller sheath catheter, and reduces the operation difficulty.
