PROBLEM TO BE SOLVED: To provide an ultraviolet sterilization device using a deep ultraviolet light emission diode as an ultraviolet light source, capable of sterilizing surely.SOLUTION: An ultraviolet sterilization device comprises: a deep ultraviolet light source comprising one or more deep ultraviolet light emission diode, and emitting deep ultraviolet to a sterilized object; and control means. The control means is configured to control one or more selected from (1) a radiation time t (unit:second) defined as a time for radiating the deep ultraviolet to the sterilized object, (2) distance d (unit:cm) between the sterilized object and the deep ultraviolet light source, and (3) light emission output P(unit:mW) of the deep ultraviolet light source, and controls so that an integrated radiation amount I (unit:mJ/cm) of the deep ultraviolet radiated to the sterilized object within the radiation time becomes a predetermined prescribed value I.SELECTED DRAWING: Figure 1 |
