The syringe (51) is provided with a cylinder (51a), a plunger (51b) and a cover body (51d). The cover body (51d) has flexibility in a sliding direction of the plunger (51b), and is connected to the cylinder (51a) and the plunger (51b) and forms a sealed space (51e) surrounded by the cylinder (51a), the plunger (51b) and the cover body (51d). The cover body hermetically blocks a portion, which is on the inner wall of the cylinder (51a) and is to be brought into contact with the plunger (51b), from the atmosphere outside the cylinder (51a).</p> |
