ELECTRODE PLATE FOR ELECTROCHEMICAL MEASUREMENT, ELECTROCHEMICAL MEASURING APPARATUS HAVING THE ELECTRODE PLATE, AND METHOD FOR DETERMINING TARGET SUBSTANCE BY USING THE ELECTRODE PLATE

摘要

An electrode plate for electrochemical measurement which can detect and determine a trace of substance contained in a living body with high sensitivity. An electrode plate (10) for electrochemical measurement is provided, on the opposite sides of a substrate body (32S), with an oxidizing electrode (32W) and a reducing electrode (32w) opened through an upper layer opening (31W) and a lower layer opening (33w) of an identical area, and further provided with a plurality of through holes (32H) penetrating from the upper surface of the oxidizing electrode (32W) to the lower surface of the reducing electrode (32w). An electrode pair for developing a redox cycle effect between the oxidizing electrode (32W) and the reducing electrode (32w) is formed by applying a potential for having an oxidizing reaction of a reduced form proceed to the oxidizing electrode (32W) and applying a potential for having the reducing reaction of an oxidized form proceed to the reducing electrode (32w).
