Abstract
PURPOSE: To enhance gas detection sensitivity and improve stability for a long time under a high temperature, by providing a catalyst layer of a specific composition on the gas sensing material surface.
CONSTITUTION: A pair of electrodes 2 is provided on the outside surface of cylindrical insulating substance 1, and gas sensing material 3 is so provided that cylindrical insulating substance 1 and electrodes 2 may be covered with material 3, thus obtaining gas-sensitive element 4. Catalyst layer 5 consisting of aluminium nitride where one kind of material, at least, selected from platinum, palladium, rhodium, rhenium, and their compounds is carried is provided on the surface gas sensing material 3. Otherwise, catalyst may be added to gas sensing material 3.
