The syringe comprises a cylinder having a front end part at one end and an opening part at another end and a bypass running in the longitudinal direction near the central position of the cylinder on the inner wall within the cylinder. A first sealing stopper is adapted, at a position toward the opening part of the cylinder from the bypass within the cylinder, to form a first compartment between the front end of the cylinder and the first sealing stopper. A second sealing is stopper adapted, at a position toward the opening part of the cylinder from the first sealing stopper within the cylinder, to form a second compartment between the first sealing stopper and second sealing stopper. One or more bypasses are provided in a concave form on the inner wall surface of the cylinder, and the outer circumference of the cylinder has a smooth cylindrical shape.
