ABSTRACT:
A gas sensor has a sensor element inserted in a cylindrical housing. A measured gas cover, provided at a distal end side of the housing, forms a measured gas environment at a distal end side of the sensor element. An atmospheric air cover, provided at a proximal end side of the housing, forms an atmospheric air environment at a proximal end side of the sensor element. A clearance between an inside surface of the housing and an outside surface of the sensor element is gastightly sealed with a sealing member including a plurality of powder filler layers to separate or isolate the measured gas environment from the atmospheric air environment.
