Abstract
PURPOSE: To enable to detect combustible gas only without being affected to the moisture, by providing the gas transmission electric insulation layer on the surface of gas sensing layer and providing the adsorption layer having gas transmission and water adsorption performance on the layer, in the gas detection element taking N type semiconductor as major content.
CONSTITUTION: On the surface of gas sensing layer obtained with molding and baking the powder of SnO2, ZnO, γ-Fe2O3 and so on, the electric insulation layer having gas transmission such as SiO2 is placed with sputtering method. The adsorption layer which transmits gas and adsorbs water content, such as perforated film of Na2O.nSiO2 is placed on the electric insulation layer to constitute gas detection element.
