Abstract

To provide an electron beam irradiation device capable of improving discharge performance of liquid from an irradiation chamber.SOLUTION: The shielding body 32 includes a first divided body 41, a second divided body 42 forming the irradiation chamber 31 by being combined with the first divided body 41, and an auxiliary shielding part 44 covering the outdoor side of the irradiation chamber 31 at a joint 43 which is a boundary part between the first divided body 41 and the second divided body 42. The seam 43 of the shield 32 has a lower surface region 43a located on the lower surface of the shield 32 in the vertical direction Da. The auxiliary shielding part 44 includes a lower shielding part 51 for covering the outdoor side of the irradiation chamber 31 in the lower surface part 43a of the joint 43. The lower shield part 51 includes a discharge passage 61 for discharging the liquid flowing out to the outside of the irradiation chamber 31 from the inside of the irradiation chamber 31 through the lower surface region 43a of the joint 43.SELECTED DRAWING: Figure 2
