PROBLEM TO BE SOLVED: To prevent entering of a foreign matter from the outside of a reaction vessel, and to prevent environmental pollution to the outside. SOLUTION: This reaction vessel includes a sealed reaction chamber 5, reaction chamber channels 13, 15, 17 connected to the reaction chamber 5, and a syringe 51 for sending liquid to the reaction chamber channels 13, 15, 17 and the reaction chamber 5. The syringe 51 includes a cylinder 51a, a plunger 51b and a cover body 51d. The cover body 51d has flexibility in the sliding direction of the plunger 51b, forms a sealing space 51e enclosed by the cylinder 51a, the plunger 51b and the cover body 51d in the connected state to the cylinder 51a and the plunger 51b, and blocks a part in contact with the plunger 51b on an inner wall of the cylinder 51a from the atmosphere outside the cylinder 51a, while keeping airtightness.
