PROBLEM TO BE SOLVED: To provide an endoscope storage cabinet capable of preventing breeding of bacteria in an internal conduit of an endoscope.SOLUTION: An endoscope storage cabinet 1 comprises: an ozone generator 25; an ozone supply pipe 34 extending through the ozone generator 25; an ozonolysis box 32 for storing an ozonolysis catalyst 61 which decomposes ozone; and a pump 24. The ozone supply pipe 34 is connected detachably to an air supply/water supply cylinder 107 which communicates with an air supply/water supply channel 105 (internal conduit) of an endoscope 100. The ozonolysis box 32 is connected to a nozzle 109 of the air supply/water supply channel 105. When the ozone supply pipe 34 and the ozonolysis box 32 are connected to the endoscope 100, a first air flow channel A is formed of the ozone supply pipe 34, the air supply/water supply channel 105, and the ozonolysis box 32. The pump 24 generates an air stream in the first air flow channel A and lets ozone generated by the ozone generator 25 flow through the air supply/water supply channel 105. Thereby, the air supply/water supply channel 105 is sterilized by the ozone. 【課題】内視鏡の内部管路での細菌の繁殖を防止できる内視鏡保管庫を提供すること。【解決手段】内視鏡保管庫１は、オゾン発生器２５と、オゾン発生器２５を経由して延びるオゾン供給管３４と、オゾンを分解するオゾン分解触媒６１を収納するオゾン分解箱３２と、ポンプ２４を有する。オゾン供給管３４は内視鏡１００の送気・送水チャンネル１０５（内部管路）に連通する送気・送水シリンダー１０７に着脱可能に接続され、オゾン分解箱３２は送気・送水チャンネル１０５のノズル１０９に接続される。オゾン供給管３４とオゾン分解箱３２が内視鏡１００に接続されると、オゾン供給管３４、送気・送水チャンネル１０５およびオゾン分解箱３２によって第１気体流路Ａが形成される。ポンプ２４は第１気体流路Ａに気流を発生させてオゾン発生器２５で発生したオゾンを送気・送水チャンネル１０５に流す。オゾンにより送気・送水チャンネル１０５が殺菌される。【選択図】図２
