To provide a potential measuring device with which it is possible to further improve evaluation quality.SOLUTION: There is provided a potential measuring device comprising: a plurality of readout electrodes arranged in an array form, for detecting a potential at an action potential generation point that is generated by cell activity; an insulating member; a reference electrode for detecting a reference potential; and an amplification unit for obtaining a potential difference between a detected potential by the readout electrodes and a detected potential by the reference electrode. The readout electrodes have a covered area where the insulating member is laminated on the readout electrodes, and an open area where the insulating member is not laminated on the readout electrodes, the readout electrodes having, in the open area, at least one high part whose height is high and/or at least one low part whose height is low, with the face of the readout electrodes laminated with the insulating member as a point of reference.SELECTED DRAWING: Figure 1 【課題】評価品質を更に向上させることができる電位測定装置を提供すること。【解決手段】アレイ状に配置され、細胞の活動によって発生する活動電位発生点の電位を検出する複数の読み出し電極と、絶縁部材と、参照電位を検出する参照電極と、読み出し電極による検出電位と参照電極による検出電位との電位差を得る増幅部と、を含み、該読み出し電極が、該読み出し電極に該絶縁部材が積層された被覆領域と、該読み出し電極に該絶縁部材が積層されていない開口領域とを有し、該読み出し電極が、該開口領域に、該読み出し電極の該絶縁部材との積層面を基準にして、高さが高い少なくとも１つの高部及び／又は高さが低い少なくとも１つの低部を有する、電位測定装置を提供する。【選択図】図１
