Abstract

PURPOSE: To protect the catalyst from poisoning by the phosphorus by providing the protective layer at the upper part of the catalyst layer, thus ensuring the sufficient showing of the catalyst function.
CONSTITUTION: The solid state electrolyte of zirconia or the like is formed to the tubular container 1 with one end closed. And the inside of such solid state electrolyte container 1 is used as the standard ocygen partial pressure dividion side; while the outside of container is set as the measurement side to receive the contact to the exhaust gas. Then the oxygen sensor element containing inside and outside electrodes 2 and 3 which are formed by the platinum on the inner and outer surfaces of ontainer 1 is fixed into housing 4 made of the metal which is hard to be oxidized and deformed even at a high temperature. Container 1 is covered around by outer and inner louvers 16' and 16 each since it is fragile.
