Abstract
A protective layer of zirconia particles having particle sizes of 0.5-5 .mu.M is provided on a surface of an electron-conducting layer of an oxygen sensor at a side of a gas whose oxygen concentration is to be detected to a thickness of 4-100 .mu.M by bonding zirconia particles to one another and the first electron-conducting layer by 10-30% by weight of a high melting point adhesive, such as powders of borosilicate glass, based on total weight of the zirconia particles.
