PROBLEM TO BE SOLVED: To provide an electrochemical sensor having a wide margin for the formation range and formation position of a silver chloride electrode (Ag/AgCl electrode), allowing elution of silver chloride to be suppressed, and resulting in the stable electric potential of the silver chloride electrode.SOLUTION: An electrochemical sensor includes: a substrate 11; a conductor 23a arranged on the substrate 11; an insulation layer 30 covering the conductor 23a with part of the conductor 23a being exposed; a silver chloride electrode 23 formed at least on the exposed section of the conductor 23a; and an organic layer 32 covering the silver chloride electrode 23 and having water permeability.SELECTED DRAWING: Figure 1 |
