PROBLEM TO BE SOLVED: To provide a scheme for reducing concentration of a sterilizing agent entering a sterilizing chamber through a passage by setting a catalyst to decompose the sterilizing agent in the passage through which air contained in a liquid reservoir is sucked into the depressurized sterilizing chamber.SOLUTION: A sterilization apparatus for sterilizing an object in a sterilizing chamber using a sterilizing agent includes a liquid reservoir to store the liquid sterilizing agent, the sterilizing chamber to contain the object, a first passage through which the liquid sterilizing agent stored in the liquid reservoir is introduced to the sterilizing chamber, a second passage through which a gas in the liquid reservoir is sucked into the sterilizing chamber before the liquid sterilizing agent stored in the liquid reservoir is introduced to the sterilizing chamber, and a catalyst for decomposing a sterilizing component in the sterilizing agent that is set in the second passage.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】液溜り部に含まれる空気を、減圧された滅菌室に吸い出す経路内に、滅菌剤を分解する触媒を設けることで、当該経路から滅菌室内に入る滅菌剤の濃度を低減可能にさせる仕組みを提供すること。【解決手段】 滅菌剤を用いて滅菌室内の対象物を滅菌する滅菌装置であって、液体の滅菌剤を溜める溜り部と、前記対象部が収容される前記滅菌室と、前記溜り部に溜められた液体の滅菌剤を前記滅菌室に導入する第1経路と、前記溜り部に溜められた液体の滅菌剤を前記滅菌室に投入する前に、前記溜り部内の気体を前記滅菌室に吸い出す第2経路と、前記第2経路内に設けられた、前記滅菌剤の滅菌成分を分解するための触媒と、を備えることを特徴とする。【選択図】 図2
