摘要： A fluid sterilization device with a small channel tube is provided. The fluid sterilization device includes a channel tube through which a fluid flows, and a light source unit that irradiates an inside of the channel tube with an ultraviolet ray. The channel tube includes a transparent tube transmitting the ultraviolet ray, and a reflector formed of an unsintered PTFE film, disposed in contact with an outer peripheral surface of the transparent tube, and reflecting ultraviolet rays transmitted through the transparent tube. The reflector is formed by laminating a plurality of unsintered PTFE films so that facing surfaces of the unsintered PTFE films are in close contact with each other.
