特徴とする酸素濃度検出装置。[Scope of Claim for Utility Model Registration] A tubular element made of a zirconia solid electrolyte that exhibits an electromotive force according to the difference between the oxygen concentration in exhaust gas and the oxygen concentration in the atmosphere, and which is closed at one end, and an exhaust gas of the element. An electrode consisting of a platinum layer that covers the outer surface on the gas side and the inner surface on the atmosphere side, a protective layer that covers most of the electrode on the exhaust gas side and protects the electrode, and an electromotive force generated in the above element. In an oxygen concentration detection device comprising a ring member for transmitting information from the end of the electrode where the protective layer does not exist to the support part that supports the element, the lower part of the ring member extends downward and is arranged so as to overlap with the protective layer. An oxygen concentration detection device characterized by having a protruding portion.
