ABSTRACT:
In an oxygen sensor that measures a limiting current of when a voltage is applied between pumping electrodes, and also performs a rich/lean judgment based on an electromotive force generated between one of the pumping electrodes and a reference electrode, an oxygen supply voltage for supplying oxygen to the reference electrode is applied, and the reference electrode is covered with a dense layer.
