Abstract
PURPOSE: To form a humidity sensing element which stably and surely operates from low humidity up to high humidity and is regenerative through thermal cleaning by using porous electrodes having pore diameters larger than the pore diameters of porous humidity sensing ceramics.
CONSTITUTION: Porous humidity sensing ceramics 101 of mean pore diameters above 2μ and porosities about 10 to 40% composed of simple metal compound base ceramics, spinel base ceramics or other is provided with porous electrodes 102 of mean pore diameters above the mean pore diameters of the abovementioned humidity sensing ceramics and about 10μ or under and thicknesses about 0.1 to 50μ composed of metals such as silver, nickel or the other, metal oxides such as nickel oxide, zinc oxides or other, whereby the humidity sensing element is provided.
