To provide an electrochemical measurement device which can further increase the efficiency of cleaning an electrode by an electrolytic polishing.SOLUTION: The valve 14 of a branch flow path is closed while an electrolytic polishing controller 512 is applying a voltage for an electrolytic polishing to a work electrode 32 through a measurement circuit 4, so that a sample solution in the branch flow path and in a flow cell is stopped. The valve 14 of the branch flow path is opened while the electrolytic polishing controller 512 is not applying a voltage for an electrolytic polishing to the work electrode through the measurement circuit 4, and a liquid replacement in the branch flow passage and in the flow cell is performed.SELECTED DRAWING: Figure 2 【課題】電解研磨による電極の洗浄効率を従来よりも向上させる電気化学測定装置を提供する。【解決手段】電解研磨制御部５１２が測定回路４を介して作用電極３２に電解研磨のための電圧を印加している間、分岐流路のバルブ１４を閉じて、分岐流路及びフローセル内の試料溶液の流れを止める。電解研磨制御部５１２が測定回路４を介して作用電極に電解研磨のための電圧を印加していない間は、分岐流路のバルブ１４を開けて、分岐流路及びフローセル内の液置換を行った。【選択図】図２
