摘要： PROBLEM TO BE SOLVED: To provide a comparison electrode which has a simple structure and is easy to achieve a compact size.
SOLUTION: The comparison electrode includes a cylindrical member 2 made of silver, a silver halide layer 3 formed on the inner surface of the cylindrical member, an insulating layer 4 formed on the outer surface of the cylindrical member, and a hydrophobic ion liquid 5 filling the internal space of the cylindrical member. Since the hydrophobic ion liquid keeps a contact with a sample solution, the comparison electrode can almost entirely eliminate the problems, which a conventional comparison electrode 1 faces, of the sample solution contamination due to the internal liquid of high-concentration KCl solution etc., and the potential difference between the internal liquid and the sample solution.
