摘要：
An oxygen sensor of a limiting current type includes a sensing element coated with a porous coating layer having a catalyst supported thereon. The catalyst includes at least one element selected from the group consisting of platinum, rhodium, palladium, iridium and ruthenium, and the content of the catalyst is not more than 50 wt % with respect to the total weight of the porous coating layer, and particles of the catalyst are dispersed within the porous coating layer at spacings of not more than 6 .mu.m. By using the catalyst, the influence of hydrocarbons to the oxygen concentration is reduced.
