Provided is an electron beam irradiation device that is capable of uniformly irradiating the entire outer surface of a container with electron beams using small-sized low-energy electron accelerators, and is able to maintain the reliability and safety of the sterilization effect at high levels by sterilizing each part to be sterilized to equal degrees, and is also able to keep the initial costs and maintenance costs of the device low by reducing the costs of the electron accelerators and extending the usage limit (service life) of the electron accelerators. When the side surface portions of the container are irradiated with electron beams with the bottom surface portion of the container supported by a support means, the position of the container is moved by the support means so that the distances between the side surface portions of the container and irradiation windows of the electron accelerators are substantially equal. Next, when an upper surface portion and the bottom surface portion of the container are irradiated with electron beams with the side surface portions of the container held by a holding means, the position of the container is moved by the holding means so that the distances between the upper surface portion and the bottom surface portion of the container and the irradiation windows of the electron accelerators are substantially equal.La présente invention concerne un dispositif dirradiation par faisceau délectrons qui est capable dirradier uniformément la totalité de la surface externe dun récipient avec des faisceaux délectrons en utilisant des accélérateurs délectrons de faible énergie de petite taille, et est capable de maintenir la fiabilité et la sécurité de leffet de stérilisation à des niveaux élevés par stérilisation de chaque article à stériliser à des degrés égaux, et est également capable de maintenir les coûts initiaux et les coûts de maintenance du dispositif à un niveau bas en réduisant les coûts des accélérateurs délectrons et prolon
