Abstract
To provide a fluid sterilization device that can increase the number of units produced per unit of time. [Solution] The fluid sterilization device 1 has a sterilization chamber 60 for sterilizing the flowing fluid, and comprises a sterilization chamber body 10 in which at least the inner wall surface 61 of the sterilization chamber 60 is formed of polytetrafluoroethylene, and a light source unit 20 including a light-emitting element 22 that emits ultraviolet light into the sterilization chamber 60. The inner wall surface 61 of the sterilization chamber 60 has a root mean square wavelength Rλq measured by a contact-type roughness meter that is greater than 100 μm, or a root mean square wavelength Rλq measured by a laser microscope that is greater than 70 μm.
