An electron beam sterilization device (1) includes a rotational member (22) that rotates around vertical rotational shafts (33), (34), and the rotational member (22) includes an upper stage (25), a middle stage (27), and a lower stage (26). On the upper stage (25), there are provided a plurality of electron beam emission units (15) arranged along the circumferential direction. On the middle stage (27), there is provided a retaining device (17) that retains a container (2). On the lower stage (26), there are provided a plurality of power supply units (71) that supply power to the electron beam emission units (15). Power supply cables (72) extend from the power supply units (71) to the upper stage (25) along the rotational shafts (33), (34) and are connected to the electron beam emission units (15).
