PROBLEM TO BE SOLVED: To provide a galvanic cell oxygen sensor that can suppress a reaction in a positive electrode different from a reaction under normal conditions while suppressing the exhaustion of an electrode material.SOLUTION: The galvanic cell oxygen sensor comprises the positive electrode, a negative electrode, an electrolytic solution, and a diaphragm. An oxygen concentration detected before a normal use is suppressed to be 0.1 vol.% or more and 4.0 vol.% or less. |
