PROBLEM TO BE SOLVED: To provide a filtering tool for filtering the gas discharged from a washing tank without applying loads to the top cover, etc., to close the washing tank, and also to provide an endoscope reprocessor equipped with such a filtering tool.SOLUTION: The filtering tool comprises: an introduction port 116 a discharge port 21 a filtration channel connecting the introduction port 116 and the discharge port 21 with airtight walls and a filtering member 30 filled in the filtration channel. The filtering member 30 includes: a deformation part 31 which is compressed to form a void in the filtration channel when the pressure inside the filtration channel exceeds a predetermined value and a non-deformation part 32 which keeps its shape even if the pressure inside the filtration channel exceeds the predetermined value and the whole or a portion of which is disposed at least between the void and the introduction port or between the void and the discharge port.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2017,JPO&INPIT【課題】洗浄槽を閉じるトップカバー等に負荷が加わらず、かつ洗浄槽から排出される気体を濾過する濾過具及び濾過具を備えた内視鏡リプロセッサを提供する。【解決手段】導入口116と、排出口21と、導入口116と排出口21とを気密な壁で繋いだ濾過路と、濾過路に充填された濾過材30と、を含む濾過具であって、濾過材30は、前記濾過路内が所定圧力を超えると圧縮して濾過路内に空所を形成する変形部31と、濾過路内が所定圧力を超えても形状を保持し、少なくとも、前記空所と前記導入口との間、または、前記空所と前記排出口との間に、全部または一部が配置される非変形部32と、を含む。【選択図】図6
