Zusammenfassung:PURPOSE:To obtain an inexpensive, accurate, and reliable hygrometer which has a low resistance, has a proper resistance change width, is highly durable and reliable, and can produce a moisture measuring circuit easily. CONSTITUTION:A solution containing manganese acetate and lead acetate is applied onto an alumina substrate 4 with a comb-shaped electrode 2 by dip coating. The coated substrate is heat-treated to form a humidity element composed mainly of heat-treated manganese oxide and lead oxide.
