There is provided a solid-contact ion-selective electrode having a high potential stability and potential reproducibility. The ion-selective electrode includes an ion sensitive film having a Group-1 element ion, a Group-2 element ion, a hydronium ion or an ammonium ion as a target ion, an ion occluding material layer, and a conductive electrode, wherein the ion occluding material contained in the ion occludes material layer occluding the target ion, the ion occluding material being a Prussian blue analog represented by the structure formula AM[M'(CN)]&#x25a1;.kHO. Herein, A is one type or a plurality of types of Group-1 elements, Group-2 elements, hydronium, or ammonium; M and M&#x2032; are one type or a plurality of types of transition metals; M or M&#x2032; includes at least one of nickel, cobalt, copper, silver, and cadmium; &#x25a1; is a vacancy in a porous coordination polymer; x and y are greater than zero; and a, z, and k are numbers equal to or greater than zero.

The system includes an electronic measuring apparatus for receiving an electrochemical sensor including a substrate that carries the current collectors for connecting the measuring and reference electrodes to the measuring apparatus. The measuring electrode is coated with a reagent including at least the specific enzyme of the biological compound to be analysed in a body fluid. The measuring apparatus can impose at least two different temperatures to enable the signal from the compound to be analysed from those of other biological compounds interfering with the signal. Application to measuring glucose in the blood with glucose dehydrogenase as the enzyme, without interference with maltose.
