PROBLEM TO BE SOLVED: To provide a method that reduces a risk of disconnection of an electric wire and heightens a sterilization effect to an object to be sterilized by properly heating the inside of a sterilization chamber.SOLUTION: A sterilization system that sterilizes an object to be sterilized housed in a sterilization chamber by depressurizing the sterilization chamber includes the sterilization chamber in which the object to be sterilized is housed, a heating part for heating using an electric current, a heating part power source that supplies an electric current to the heating part, a depressurizing means for depressurizes the inside of the sterilization chamber and a power supply unit that makes a supply of an electric current to the heating part from the heating part power source possible by depressurizing the inside of the sterilization chamber by the depressurizing means.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2017,JPO&INPIT【課題】 電線の断線のおそれを低減可能とすると共に、滅菌室内を好適に加温して被滅菌物に対する滅菌効果を高めること。【解決手段】 滅菌室を減圧して前記滅菌室に収容される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、電流を用いて加熱する加温部と、前記加温部に電流を供給する加温部電源と、前記滅菌室内を減圧する減圧手段と、前記減圧手段による前記滅菌室内の減圧により、前記加温部電源から前記加温部への電流の供給を可能とする電源供給ユニットと、を備えることを特徴とする。【選択図】 図8
