出器。[Claims for Utility Model Registration] A pair of electrodes are formed on both sides of first and second plate-shaped oxygen ion permeable solid electrolytes, and the first and second solid electrolytes are placed on one side of each. A space with at least one end open is provided between the formed electrodes, and the electrodes are overlapped with each other, and the electrode formed on the surface of the first solid electrolyte opposite to the space is brought into contact with the atmosphere. An oxygen pump is configured by connecting electrodes formed on both sides of the second solid electrolyte to a DC power source, and a sensor element is configured by connecting electrodes formed on both sides of the second solid electrolyte to a voltage source to configure a limiting current type oxygen sensor. An air-fuel ratio detector characterized by:
