PROBLEM TO BE SOLVED: To provide an electron ray sterility device capable of performing sterility properly to a container having a large volume shape.SOLUTION: An electron ray sterility device 1 comprises: a container holding part 2 for holding a container B; an electron ray irradiation part 3 for irradiating electron ray to the inside of the container B held by the container holding part 2. The electron ray sterility device further comprises: a movement control part 4 for controlling a movement of the container B held by the container holding part 2; and an attitude control part 5 for controlling an attitude of the container B held by the container holding part 2. The movement control part 4 and the attitude control part 5 respectively control the movement and the attitude of the container B so that the electron ray is irradiated to the inside of the container B in an approximately uniform state, and the electron ray irradiation part 3 has a nozzle n for emitting the electron ray from a tip end t which is inserted into a mouth m of the container B, and the movement of the container B controlled by the movement control part 4 is rotation of the container B around the mouth m, and the attitude of the container B controlled by the attitude control part 5 is an inclined state that an axis Cb of a trunk b is inclined by a predetermined angle &thetas; to an axis Cn of the nozzle n. |
