1. An all-solid-state ion-selective electrode including a working electrode and an ion responsive membrane, the all-solid-state ion-selective electrode comprising:
an ion-electron conversion layer disposed between the working electrode and the ion responsive membrane and electrically connecting the working electrode and the ion responsive membrane to each other,
wherein the ion-electron conversion layer contains an ion-electron conversion substance and a polymer or contains a polymer having an ion-electron conversion function, and
wherein the polymer has resistance to a solvent used in manufacturing the ion responsive membrane.
