Assignee: TOHOKU UNIVERSITY
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 4:
5. 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 includes both an electrode located in the same plane as the working electrode and an electrode disposed above the plane and having a three-dimensionally extending structure.
