PROBLEM TO BE SOLVED: To provide a closed vessel for steam treatment that treats an object article by bringing it into contact with steam under pressure and prevents deviation of heat distribution to suppress heat strain of the vessel while positively controlling (heating, cooling) of the temperature in the vessel.SOLUTION: A closed vessel 10 treats an object article 1 by bringing it into contact with steam under pressure after an upper vessel 9 closes a lower vessel 8. A plurality of passages are formed from an introduction port 202 toward an exhaust port 204 in the upper vessel 9 serving as a passage of a fluid flowing from the introduction port 202 toward the exhaust port 204. The passages are designed so as to have a nearly equal surface area of fluid contact from the introduction port 202 toward the exhaust port 204.SELECTED DRAWING: Figure 2 【課題】加圧下において被処理物を水蒸気に接触させて処理することが可能な密閉容器であって、密閉容器内の温度制御（加熱・冷却）を積極的に行いつつも、密閉容器に対する熱分布の偏りを防ぎ、密閉容器の熱ひずみを抑制することが可能な水蒸気処理用の密閉容器を提供する。【解決手段】下部容器８に対して上部容器９が閉じられた後、加圧下において被処理物１を水蒸気に接触させて処理することが可能な密閉容器１０であって、上部容器９には、導入口２０２から排出口２０４に向かう流体の流路として、導入口２０２から排出口２０４に向けて複数の経路が形成されており、この複数の経路は、導入口２０２から排出口２０４に向かうまでに流体が接する表面積が略均等となるように構成されている。【選択図】図２
