PROBLEM TO BE SOLVED: To provide a fine bubble generation nozzle for largely enhancing a generation rate of a fine bubble of a micro-level and a nano-level.SOLUTION: A fine bubble generation nozzle 1 is provided with an introduction chamber 20 for introducing a gas-liquid mixed body, a turning chamber 30 for turning the gas-liquid mixed body L flowed out of the introduction chamber 20, a derivation flow passage 61 for deriving the turned gas-liquid mixed body L, a branch flow passage 62 for branching off from the derivation flow passage and a circulation flow passage 66 for circulating the gas-liquid mixed body L of reaching the downstream side of the derivation flow passage to the upstream side of the derivation flow passage 61 without flowing in the branch flow passage. According to this nozzle 1, since a fine bubble is generated by circulating the gas-liquid mixed body L of not generating the fine bubble, the fine bubble can be generated in large quantities.SELECTED DRAWING: Figure 1 【課題】マイクロレベルおよびナノレベルの微細気泡の発生割合を大幅に高めた微細気泡発生ノズルを提供する。【解決手段】気液混合体を導入する導入室２０と、導入室２０から流出した気液混合体Ｌを旋回させる旋回室３０と、旋回した気液混合体Ｌを導出する導出流路６１と、導出流路から分岐する分岐流路６２と、分岐流路へ流入せずに導出流路の下流へ到達した気液混合体Ｌを導出流路６１の上流へ循環する循環流路６６とを備えることを微細気泡発生ノズル１による。このノズル１によれば、微細気泡が生成されなかった気液混合体Ｌを循環させて微細気泡を生成するので、大量に微細気泡を生成することができる。【選択図】図１
