Abstract
A selective ion sensitive electrode is so constructed that an ion exchanger sensitive to a specific ion is formed on a metal electrode, an electric conductive resin electrode or a chlorinated metal electrode to which a signal wire is connected so as to maintain a stable electric connection between the signal wire and the ion exchanger over a long period of time. A layer of a silane coupling agent is used between the electrode member and ion exchanger.
