Abstract
A potential measurement device includes a plurality of read-out electrodes arranged in an array shape and that detects a potential at a potential generation point generated due to a chemical change, and a reference electrode that detects a reference potential. The reference electrode is arranged within the array of the read-out electrodes. With this configuration, a low-noise potential measurement device in which noise superimposed on a wire from each of the read-out electrodes to an amplifier and noise superimposed on a wire from the reference electrode to the amplifier, i.e., wiring noise, can be reduced is achieved.
