摘要

An ion selective electrode device is used to electrochemically detect several ion concentrations of an ion-containing liquid. The ion selective electrode device comprises a plurality of ion selective electrodes. These ion selective electrodes each include a substrate of insulating material having a small-diameter through hole, a metal layer formed in one body on an inner peripheral surface of the through hole and both major surfaces of the substrate, and ion sensitive layer formed on the metal layer of the inner peripheral surface. Those ion selective electrodes are connected by insulating plates for maintaining electrical insulation between the adjoining ion selective electrodes in such a manner that these through holes define a flow path for liquid to be examined.
