PROBLEM TO BE SOLVED: To provide an electrode device for measuring electric potential, which can be controlled easily during storage, while suppressing elongation of time required until reaching a measurable state after stabilization of an electric potential.SOLUTION: An electrode device 1 for measuring electric potential includes: an electrode 12 containing silver chloride; a housing 11 covering the electrode 12, and having openings 111, 112 for circulating external water therethrough; and a solid chloride 13 arranged inside the housing 11, for dissolving into water and supplying chloride ions into the housing.SELECTED DRAWING: Figure 2 |
