1. An ion sensor comprising:
- an electrically conductive substrate;
a redox layer coating a surface of said electrically conductive substrate;
a barrier layer coating a surface of said redox layer; and
an ion-selective layer coating a surface of said barrier layer;
said barrier layer made from a material which functions to prevent mutual contamination between said ion-selective layer and said redox layer with substances constituting these layers, and to transmit a potential produced in said ion-selective layer by contact with an ion from said ion-selective layer to said redox layer.

Abstract
An ion sensor includes an electrically conductive substrate, a redox layer coating the surface of the electrically conductive substrate, a barrier layer coating the surface of the redox layer, and an ion-selective layer coating the surface of the barrier layer. The barrier layer functions to prevent migration between the ion-selective layer and redox layer of substances constituting these layers, and to transmit a potential difference produced in the ion-selective layer by contact with an ion from the ion-selective layer to the redox layer.
