    摘要： A fine bubble generator for generating fine bubbles in a liquid without externally introducing gas. According to an embodiment, a liquid flows in a gap between a first helical part on an inner surface of an outer member having a tubular shape and a second helical part on an outer surface of an inner member in the outer member, so that cavitation occurs because of the decrease in pressure when the liquid flows out of the gap between the first helical part and the second helical part, and fine bubbles are generated in the liquid. In this process, the liquid flowing near the inner surface of the outer member swirls along the first helical part, and the liquid flowing near the outer surface of the inner member swirls along the second helical part, and cavitation is promoted by the swirl flows, and the amount of fine bubbles generated is increased.
