Abstract
A reference electrode traps silver ions and chloro complex ions leaching to an internal filling solution so that the blocking of the liquid junction can be prevented. A silver/silver chloride electrode can be provided as an internal electrode in an internal filling solution; and a tube which houses, in order from top to bottom, the internal electrode, an inorganic cation exchanger for trapping silver ions and/or chloro complex ions from leaching from the internal electrode, and a ceramic member for preventing the diffusion of the silver ions and/or the chloro complex ions to the internal filling solution.
