摘要：
An oxygen sensor having an oxygen-ion-conductive element made of a metal oxide with an outer electrode composed of three layers, one of which is the thinnest, second of which is the intermediate in thickness and the third of which is the thickest. This oxygen sensor maintains quick response characteristics over a long period of time.
