装置。[Scope of Claim for Utility Model Registration] (1) An oxygen concentration detection element that is protruded into the exhaust gas passage of an internal combustion engine and generates an output proportional to the oxygen concentration of the exhaust gas, and a protective member that surrounds the oxygen concentration detection element. The protection member includes an inner protection tube having an exhaust gas passage hole, and an outer protection tube having an exhaust gas passage hole and surrounding the inner protection tube with a predetermined gap between the inner protection tube and the inner protection tube. The exhaust gas passage hole of the pipe and the exhaust gas passage hole of the outer protection tube are arranged so as not to face each other, and the exhaust gas passage hole of the outer protection tube is oriented in a direction other than the upstream direction of the exhaust flow in the exhaust gas passage. An oxygen concentration detection device characterized in that the device is provided with an oxygen concentration detection device. (2) The oxygen concentration detection element includes a pair of elements each having an electrode layer provided on both main surfaces of one end in the longitudinal direction of a longitudinal oxygen ion conductive solid electrolyte plate, arranged in parallel so that the main surfaces thereof face each other. Registration of a utility model characterized in that the two elements are combined with a gap provided at one end, one element is used as an oxygen pump element, and the other element is used as a battery element for measuring oxygen concentration ratio. An oxygen concentration detection device according to claim 1.
