PURPOSE:To easily and quantitatively determine even a sample having high viscosity with high accuracy by providing a water-absorptive high polymer layer on the surface of an electrode system, providing a filter layer and a guide layer for liquid on the electrode system and integrating them with a porous body. CONSTITUTION:The electrode system consisting of a counter electrode 2, a measuring electrode 3, and a reference electrode 4 is formed on an insulating substrate 1 and then an insulating layer 5 is formed covering the electrode system partially except parts 2'-4' which operate electrochemically. A cellulose water-absorptive high polymer layer is provided on the surfaces of electrode systems 2'-4', a groove is formed on the electrode systems with both-sided adhesive tapes 6, and a couple of cellulose tapes are installed thereupon across the electrodes to form guide layers 7. Then a polycarbonate porous film 8 is adhered on a holding frame 9 and fixed with the both-sided adhesive tape 6 while covering the electrodes 2'-4', thereby forming the filter layer 8. Further, a porous body 10 is placed at the hole part of the holding frame 9 and a resin- made cover 11 which has a hole part having a diameter smaller than the porous body is adhered to integrate the entire body. |
