ELECTROCHEMICAL MEASUREMENT DEVICE AND ELECTROCHEMICAL MEASUREMENT SYSTEM

An electrochemical measurement device is configured to measure an activity of a biological sample with a measuring liquid having conductivity. The device includes a plate having first and second wells provided therein, a measuring electrode disposed inside the first well, and a first placement portion provided configured to have the biological sample placed thereon. The first and second wells are provided in an upper surface at positions different from each other. The plate includes a wall separating a bottom surface of the first well from a bottom surface of the second well. The measuring electrode is provided on the bottom surface of the first well around the first placement portion. The second well is configured to have a counter electrode disposed therein. The first and second wells are configured to contain the measuring liquid therein. A portion of the measuring liquid contained in the first well is electrically connected to a portion of the measuring liquid contained in the second well. This electrochemical measurement device can perform electrochemical measurement in plural wells in a short time.
