An improved reference electrode assembly is provided to solve blockage problems that can occur upon contamination of the internal solution in a housing member. An absorbent means can be provided for removing silver ions through the reaction of an alkali metal ion with a tetraphenylborate ion to produce a compound larger than that of a silver ion and a tetraphenylborate ion. The absorbent material can, for example, be a porous activated carbon or a silica gel, and can be positioned between the internal electrode of the reference electrode assembly and the liquid junction.
