ABSTRACT:
A process for fabricating a humidity-sensing element comprises forming an electrode layer on at least one side of a ceramic substrate, applying to the electrode layer a humidity-sensitive paste containing a zirconia, zirconia-yttria, or yttria ceramic as a humidity-sensitive material, drying the coat, and then firing it at a temperature of 750.degree. to 870.degree. C. to form a humidity-sensing part.
