The electron beam sterilization apparatus of the present invention receives the preform PF as a sterilization target, and then receives the preform PF from the gripper group 27C and the gripper group 27C that conveys the preform PF while gripping the preform PF to the grip replacement position. Electrons that irradiate the electron beam EB to the gripper group 29C that conveys the preform PF toward the downstream while gripping the preform PF and the preform PF that passes through the electron beam irradiation area EA including the gripping position and the front and back of the gripping position. A line irradiation unit 20.本発明の電子線殺菌装置は、殺菌対象物であるプリフォームＰＦを受け取った後に、掴み換え位置までプリフォームＰＦを把持しながら搬送するグリッパ群２７Ｃと、グリッパ群２７ＣからプリフォームＰＦを受け取った後に、プリフォームＰＦを把持しながら下流に向けて搬送するグリッパ群２９Ｃと、掴み換え位置と掴み換え位置の前後を含む電子線照射領域ＥＡを通過するプリフォームＰＦに電子線ＥＢを照射する電子線の照射部２０と、を備える。
