PROBLEM TO BE SOLVED: To provide an electron beam irradiation device which can reduce the electrification of an object to be irradiated with a simple structure when an electron beam irradiation treatment is given to the object. SOLUTION: In the irradiation with an electron beam, the object to be irradiated is set to be earthed by supporting an opening of the hollow object with a conductive support. In the transportation of the object, the transportation direction of it is set at that perpendicular to a strip electron beam flux, the central axis of the object is oriented parallel or perpendicularly to the strip electron beam flux and the opening where the bottom of the object is grounded on its front side is also turned to the back side in the transportation direction of the object. In an irradiation chamber, it is transported and is irradiated with an electron beam while blowing an argon gas from a gas supply component into the hollow object to give a sterilization treatment to it.
