To provide a technology which enables oxygen in air to be dissolved into a liquid efficiently with a simple structure.SOLUTION: An oxygen dissolution device 1 includes: an upper tank 4 having an upper surface 4c into which a liquid is injected and a bottom part 4b provided with a falling hole 9 in which the liquid falls rolling air thereinto; and a cylindrical tube 8 which extends downward from the bottom part 4 and communicates with the falling hole 9. The cylindrical tube 8 has: a cylindrical body 10; and multiple cylindrical projections 12 which are provided on an inner peripheral surface 10a of the cylindrical body 10 and generate Karman vortexes in the liquid passing through the cylinder body 10.SELECTED DRAWING: Figure 3 【課題】簡易な構成で空気中の酸素を効率よく液体に溶解させることができる技術を提供する。【解決手段】酸素溶解装置１は、液体が注入される上面４ｃ、及び空気を巻き込みながら前記液体が落下する落下孔９が設けられた底部４ｂを有する上部タンク４と、底部４から下方に延び落下孔９に連通する円筒管８と、を備える。円筒管８は、筒本体１０と、筒本体１０の内周面１０ａに設けられ、筒本体１０内を通過する液体にカルマン渦を生じさせる複数の円筒突起１２と、を有する。【選択図】 図３
