1. An electrochemical measurement device adapted to measure a current between two electrodes in an electrolytic solution, the current being produced by an oxidation or reduction reaction of a target substance generated by a specimen contained in the electrolytic solution, and the oxidation or reduction reaction being caused by applying a measuring voltage between the two electrodes, the device comprising:
the two electrodes, hereafter one being referred to as a working electrode and another being referred to as a counter electrode;
an electrolytic solution well which accommodates the electrolytic solution; and
an eliminating electrode for eliminating the target substance, wherein:
the eliminating electrode is located in the same plane as the working electrode,
the eliminating electrode has a shape like a two-dimensional grid, and
the working electrode is positioned at one of interstices of the two-dimensional grid, without contacting the eliminating electrode.
