PROBLEM TO BE SOLVED: To provide a device that prevents sticking of liquid, which drops in a sterilization chamber from a discharge passage for discharging to the sterilization chamber air contained in a passage for supplying a sterilization agent to the sterilization chamber before the sterilization agent is supplied to the sterilization chamber via the passage, to a substance to be sterilized in the sterilization chamber, and that prevents a user from contacting with a substance of the liquid.SOLUTION: A sterilization system for sterilizing a substance to be sterilized by supplying a sterilization agent to a sterilization chamber in which the substance to be sterilized is housed includes the sterilization chamber in which the substance to be sterilized is housed, a discharge passage that discharges air contained in a passage that supplies the sterilization agent to the sterilization chamber, before supplying the sterilization agent to the sterilization chamber via the passage, to the sterilization chamber, a pan that is disposed in the sterilization chamber and disposed to receive liquid dropping in the sterilization chamber from the discharge passage, and a heater for heating the pan.SELECTED DRAWING: Figure 18COPYRIGHT: (C)2017,JPO&INPIT【課題】 滅菌剤を滅菌室に供給する経路に含まれる大気を、当該経路を介して滅菌剤を滅菌室に供給する前に、滅菌室に排出する排出経路から、滅菌室内に滴下する液体が滅菌室内の被滅菌物に付着し難くすると共に、ユーザにその液体の物質に触れさせ難くするための仕組みを提供すること。【解決手段】 被滅菌物が収容される滅菌室に滅菌剤を供給して前記被滅菌物を滅菌する滅菌システムであって、前記被滅菌物が収容される前記滅菌室と、前記滅菌剤を前記滅菌室に供給する経路に含まれる大気を、前記経路を介して前記滅菌剤を前記滅菌室に供給する前に、前記滅菌室に排出する排出経路と、前記滅菌室内に設けられた受け皿であって、前記排出経路から前記滅菌室内に滴下する液体を受けるために設けられた受け皿と、前記受け皿を加熱するヒータと、を備えることを特徴とする。【選択図】 図18
