PROBLEM TO BE SOLVED: To provide a sterilization unit capable of performing sterilization treatment over a whole sterilization object uniformly and securely.SOLUTION: A sterilization unit includes: a cylindrical storage container closed at both ends and configured to house a sterilization object a ground electrode arranged along an inner peripheral surface of the storage container a high frequency power source arranged outside the storage container and configured to supply high-frequency current of 3-500 MHz and a linear electrode extending from the high frequency power source inside the storage container and arranged so as to be alienated from and oppose the ground electrode inside the storage container. In the sterilization unit, if the maximum length of the linear electrode in the storage container is regarded as L1 (m), the wavelength of high-frequency current supplied from the high frequency power source in the linear electrode is regarded as λ (m), effective power in the linear electrode is regarded as W (W), ratio L1/λ is lower than 1/4, and ratio (200-W)/L1 is over 30 and equal to or lower than 240.COPYRIGHT: (C)2014,JPO&INPIT【課題】滅菌対象物全体にわたって均一にかつ確実に滅菌処理を行うことができる滅菌装置を提供する。【解決手段】滅菌対象物を収納する、両端が閉塞された筒状の収納容器と、この収納容器の内周面に沿って設けられた接地電極と、前記収納容器の外部に設けられた、3~500MHzの高周波電流を供給する高周波電源と、この高周波電源から前記収納容器内に伸び、当該収納容器内において前記接地電極に離間して対向するよう配置された線状電極とを備えてなる滅菌装置において、前記収納容器内における前記線状電極の最大長さをL1(m)、前記線状電極における前記高周波電源から供給される高周波電流の波長をλ(m)、前記線状電極における実効電力をW(W)としたとき、比L1/λが1/4未満であり、比(200-W)/L1が30超でかつ240以下の範囲にあることを特徴とする。【選択図】図1
