PURPOSE:To provide an ion selective electrode which can be mounted/demounted easily while preventing erroneous connection. CONSTITUTION:In ion selective electrodes 21a-21c, each comprising a body 23 having a channel 7 for passing a liquid to be inspected, an ion selective reaction film 5 for selecting a specified ion from the liquid to be inspected to bring about electric response, and an electrode output part 27 projecting outward from the interior of the body 23 and delivering a response signal from the reaction film 5 to the outside of the body 23, with a plurality of electrodes 21a-21c being used in combination, at least a set of ion selective electrodes, each having one end projecting from the body 23 at a position different from the electrode output part 27 and the other end provided with an electric signal passing part 28 exposed from the body 23, are combined. The electric signal passing part 28 is connected with the electrode output part 27 or the electric signal passing part 28 of other ion selective electrode so that a signal from the electrode output part 27 of other ion selective electrode is passed. |
