PROBLEM TO BE SOLVED: To provide an ion-selective electrode excellent in mechanical strength and durability and capable of lowering manufacturing costs and expanding the range of material glass choices for a support tube.SOLUTION: The ion-selective electrode includes the support tube having at least one open end, a substrate material made of ion-conductive glass or electron-conducting glass and provided in such a way as to seal the open end of the support tube, an internal liquid filling the support tube, a responsive glass membrane formed in a surface exposed from the open end of the support tube and a surface in contact with the internal liquid among the surfaces of the substrate material, and an internal electrode immersed in the internal liquid. |
