Patent abstract

An ion sensor has a flow path through which a sample flows. An ion-exchange membrane is in contact with the sample in the sample flow path. An internal solution is provided on one side of the ion-exchange membrane. An internal electrode is provided so as to come in contact with the internal solution. The surface of the ion-exchange membrane that does not come in contact with the sample is coated with a two-liquid-mixed epoxy resin.
