The plasma is formed inside the long shaku condition narrow tube which is sterilization object ones, the plasma sterilization device in order to do the sterilization processing inside the long shaku condition narrow tube and that method is offered are designated as purpose. Especially, inside diameter being the long shaku condition narrow tube below 5mm, efficient, as it can sterilize can process, the damage is prevented vis-a-vis the inner wall of the long shaku condition narrow tube, it is possible, at the same time to control the danger of secondary infection, furthermore the plasma sterilization device which makes that pollution of the long shaku condition narrow tube with the sputtering of the electrode is controlled possible and that method is offered are designated as purpose. The long shaku condition narrow tube 1 which is sterilization object ones it is accommodation possible in order and also, internal pressure for the electrode at inside and outside 5 where adjustment possible container 2 and the said long shaku condition narrow tube is arranged at least in the end of one side and the said long shaku condition narrow tube to have specified pressure difference, when pressure inside or outside the said long shaku condition narrow tube is adjusted, it is the plasma sterilization device which features that the plasma is formed inside said long shaku condition narrow tube by impressing alternating current volts in the said electrode.滅菌対象物である長尺状細管内でプラズマを生成し、長尺状細管内部の滅菌処理を行うためのプラズマ滅菌装置及び方法を提供することを目的とする。特に、内径が5mm以下の長尺状細管であっても効率的に滅菌処理できると共に、長尺状細管の内壁に対し、損傷を防止し、かつ二次感染の危険性を抑制することが可能であり、さらに電極のスパッタリングによる長尺状細管の汚染を抑制することを可能としたプラズマ滅菌装置及び方法を提供することを目的とする。滅菌対象物である長尺状細管1を収容可能であると共に、内部圧力を調整可能な容器2と、該長尺状細管の少なくとも一方の端部に配置される電極5と、該長尺状細管の内部と外部とで所定の圧力差を有するように、該長尺状細管の内部又は外部の圧力を調整した状態で、該電極に交流電圧を印加することにより、該長尺状細管内にプラズマを生成することを特徴とするプラズマ滅菌装置である。
