To provide a plasma functional liquid production device and a method capable of introducing a plasma gas into liquid by a simple configuration, and suppressing degradation of active species, and a plant cultivation plant.SOLUTION: A plasma functional liquid production device 10 comprises: a plasma gas generation part 20 having, a first electrode 21 to which a high frequency voltage is applied, a second electrode 22 which is arranged to face the first electrode 21 through a space therebetween, and is coupled to a ground 24, and a gas supply path 26a for supplying a plasma generation gas to the space; and a plasma functional liquid generation part 30 having a plasma functional liquid generation tank 31 for storing the solvent S therein, for immersing the first electrode 21 and the second electrode 22. The plasma gas including the active species generated by generating plasma in the plasma generation gas in the space by applying the high frequency voltage between the first and second electrodes 21, 22, passes through the second electrode 22 and is introduced into the solvent S in a bubble state, thereby generating the plasma functional liquid L.SELECTED DRAWING: Figure 1 【課題】簡便な装置構成でプラズマガスを液体に導入するとともに活性種の分解を抑制するプラズマ機能液製造装置及び方法並びに植物栽培プラントを提供する。【解決手段】プラズマ機能液製造装置１０は、高周波電圧が印可される第１の電極２１と、第１の電極２１に空間を介して対向して配置され、アース２４に接続された金属製の第２の電極２２と、空間にプラズマ生成ガスを供給するガス供給路２６ａと、を備えているプラズマガス発生部２０と、溶媒Ｓを貯留して第１の電極２１及び第２の電極２２を浸漬させるプラズマ機能液生成槽３１を備えているプラズマ機能液生成部３０と、を備えている。第１の電極２１と第２の電極２２との間に高周波電圧が印加されて空間内のプラズマ生成ガス中でプラズマを発生させて生成された活性種を含むプラズマガスが、第２の電極２２を通過して気泡状態で溶媒Ｓに導入されて、プラズマ機能液Ｌが生成される構成とした。【選択図】図１
