Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the selectivity of the response of a resistance gas sensor to a specific gas or water vapor. SOLUTION: Improvement is made by selecting a specific gas detection substance which has not be known heretofore. As applications, the following items are cited: hydrocarbon in the presence of CO, H2S, SO2, chlorine, NO2, CO2(particularly, a low concentration), CFC, ammonia, free oxygen by measurement of partial pressure, and a variety of organic substance gases or vapors.
