Abstract
A reference electrode for improving a product life cycle without using a gelled hydrophobic ionic liquid having a prescribed hardness or viscosity and without having a large thickness so as to be difficult to manufacture is provided. The reference electrode is provided with a housing for accommodating an internal electrode, a filler for electrically connecting the internal electrode, and a sample liquid. The filler is formed having a layer between the internal electrode and an opening formed in the housing for contacting the sample liquid and the filler. The filler includes a first layer including a water soluble electrolytic solution formed to be in contact with the internal electrode a second layer including a hydrophobic ionic liquid formed to be in contact with the first layer; and a third layer including a gelled hydrophobic ionic liquid formed in the opening so as to be in contact with the second layer.
