Electron beam sterilization equipment includes an outer-surface sterilization zone Z2 for sterilizing the outer surface of a container B by emitting electron beams when the container B is transported along circular paths L1 and L2； and an inner-surface sterilization zone Z3 for sterilizing the inner surface of the container B. An electron beam irradiator E1 is located near the upstream side of a 1-2 joint J1-2 of the circular paths L1 and L2 disposed in the outer-surface sterilization zone Z2, and a electron beam irradiator E2 is located near the downstream side of the joint. Thus, the electron beam irradiator E1 and the electron beam irradiator E2 are brought close to each other so as to sequentially sterilize the one half outer surfaces and the other half outer surface of the container B.
