ELECTRODE PLATE FOR ELECTROCHEMICAL MEASUREMENTS, APPARATUS FOR ELECTROCHEMICAL MEASUREMENTS HAVING THE ELECTRODE PLATE, AND PROCESS FOR QUANTITATIVELY DETERMINING TARGET SUBSTANCE USING THE ELECTRODE PLATE

摘要

An object of the invention is to provide an electrode plate for electrochemical measurements for detecting with high sensitivity and determining a substance included in a living body in a slight amount.;The electrode plate for electrochemical measurements 10 of the present invention has on both faces of body of the substrate 32S, oxidation electrode 32W and reduction electrode 32w opened respectively at upper layer opening 31W and lower layer opening 33w having the same area; and further has a plurality of through-holes 32H that penetrate through from the superior face of the oxidation electrode 32W to the inferior face of the reduction electrode 32w, in which electrode pairs are formed which exhibit a redox cycle effect between the oxidation electrode 32W and the reduction electrode 32w by applying the potential which can proceed an oxidative reaction of a reductant on the oxidation electrode 32W, and the potential which can proceed a reductive reaction of an oxidant on the reduction electrode 32w.
