PROBLEM TO BE SOLVED: To provide a fine-bubble generating system in which gas such as air and oxygen gas is dissolved efficiently in a liquid such as city water and river water to clean water or revive water environment and fine bubbles can be produced efficiently by a concise structure. SOLUTION: The swirling type fine-bubble generating system is composed of: a container main unit having a conical space 100 or a sake bottle-like or wine bottle-like space; a pressurized liquid inlet 50 opened in a tangential direction on a part of the circumferential surface of the inner wall of the space; a gas introducing hole 80 opened at the bottom 300 of the space; and a swirling gas-liquid outlet 101 opened at the top of the space.
