PROBLEM TO BE SOLVED: To provide an electron beam irradiation apparatus capable of suppressing the distribution of electron beam irradiation dose to about 1.5 times in the dialyzer of dry type, for example, having a low density portion on the central portion of a cylinder and having high density portions on both the outer sides. SOLUTION: The electron beam irradiation apparatus, which is composed of cylindrical medical equipment provided with the low density portion on the central part of an object to be irradiated, which is not filled with a liquid, and the thin high density portions on both the terminal sides in the axial direction, an electron beam irradiating part for irradiating the medical equipment with the electron beams of high energy and a moving means for moving the cylindrical medical equipment in the direction crossing the irradiation area of electron beams, is provided with an inclining means for inclining the medical equipment about at 20-60 deg. in the electron beam irradiating direction without rotating the equipment. Then in the state of inclining the medical equipment by means of the inclining means, the inclined medical equipment is irradiated with the electron beams of high energy while being conveyed in a prescribed direction. |
