Problem to be solved: to provide a sterilization apparatus which reduces the risk of unsterilized substances from the sterilization vessel.Solution: the sterilization tank 2 has an opening for carrying or delivering the sterilized substance, and can be opened and closed by the door 4 (4a, 4b).The door monitoring means monitors the open state of the door 4 of the sterilization tank 2.The sterilization confirming means prompts to confirm whether or not the storage in the sterilization vessel 2 is sterilized after the completion of sterilization of the sterilized substance in the sterilization vessel 2 after the completion of detection of the opening of the door 4 by the door monitoring means after the completion of sterilization.In the case of both door type having the carrying side door 4A and the carrying side door 4b, the sterilization confirming means confirms whether or not the storage in the sterilization vessel 2 is sterilized after the sterilization of the sterilization object in the sterilization vessel 2 after the completion of sterilization of the sterilization object door by the door monitoring means is the second or later after the sterilization termination Prompt.Diagram【課題】滅菌槽内から未滅菌物が搬出されるリスクを低減した滅菌装置を提供する。【解決手段】滅菌槽２は、被滅菌物を搬入または搬出するための開口部を有し、その開口部をドア４（４Ａ，４Ｂ）で開閉可能とされる。ドア監視手段は、滅菌槽２のドア４の開閉状態を監視する。滅菌確認手段は、滅菌槽２内での被滅菌物の滅菌終了後、ドア監視手段によるドア４の開放検知が当該滅菌終了後二回目以降であるとき、滅菌槽２内の収容物が滅菌済か否かの確認を促す。搬入側ドア４Ａと搬出側ドア４Ｂとを備える両ドアタイプの場合、滅菌確認手段は、滅菌槽２内での被滅菌物の滅菌終了後、ドア監視手段による搬出側ドア４Ｂの開放検知が当該滅菌終了後二回目以降であるとき、滅菌槽２内の収容物が滅菌済か否かの確認を促す。【選択図】図１
