To allow high-sensitivity measurements to be performed inexpensively and compactly.SOLUTION: In an electrochemical measurement method of the catalyst reaction product for electrochemically measuring the catalyst reaction product produced by a catalyst reaction proceeding in a first liquid 20 and dissolved in the first liquid 20, the liquid tank 10 contains the first liquid 20 and a second liquid 30 that is in contact with the first liquid 20 by forming a liquid-liquid interface with the first liquid 20 and in which the catalyst reaction product does not dissolve, a working pole 40 is arranged in the first liquid 20, a counter electrode 50 and a reference pole 60 are arranged in the second liquid 30, and the current flowing through the working electrode 40 as the catalyst reaction product undergoes an oxidation or reduction reaction at the working electrode 40 is measured.SELECTED DRAWING: Figure 1 【課題】高感度の測定を安価かつコンパクトに実施できるようにする。【解決手段】第１の液体２０内で進行する触媒反応によって生成されて第１の液体２０に溶解している触媒反応生成物を電気化学的に測定する触媒反応生成物の電気化学的測定方法において、液槽１０に、第１の液体２０と、第１の液体２０と液液界面を形成して接し、触媒反応生成物が溶解しない第２の液体３０とを収容し、第１の液体２０内に作用極４０を配置し、第２の液体３０内に対極５０及び参照極６０を配置し、触媒反応生成物が作用極４０において酸化又は還元反応をすることで作用極４０に流れる電流を測定する。【選択図】図１
