PROBLEM TO BE SOLVED: To provide a non-heat sterilization inactivation system in which ultraviolet ray treatment and ultrafine bubble treatment are efficiently performed. A sterilization/inactivation system includes an ultrafine bubble conversion unit that converts the fine bubbles into ultrafine bubbles having a smaller diameter for a liquid containing fine bubbles, and a subsequent stage of the ultrafine bubble conversion unit. Provided, an ultraviolet irradiation unit for irradiating the liquid containing the ultra-fine bubbles with ultraviolet rays, and provided in the subsequent stage of the ultraviolet irradiation unit, and comprises a storage unit for storing the liquid, the ultra-fine bubbles, The ultraviolet ray has a diameter that does not prevent the ultraviolet ray from passing through the liquid.
