PROBLEM TO BE SOLVED: To suppress deposition of microorganisms such as algae onto an electrode device for measuring potential in a liquid.SOLUTION: An electrode device 1 for measuring potential in a liquid includes: a structure 2 in which an opening 211 that communicates inside with outside is formed and that accommodates an electrode 3 therein; a filter 4 for shielding the opening 211 of the structure 2; and an anti-microorganism material 5 that has the same ionization component as the material of the electrode 3 and is provided on the outer surface of the filter 4 or in the vicinity thereof. When silver (AgCl) is used for the material of the electrode 3, the anti-microorganism material also includes silver. |
