Abstract

PURPOSE:To achieve a higher economy and a higher versatility, by arranging several types of gas sensing bodies on several pairs of electrodes provided on an insulator. CONSTITUTION:A first gas sensing body 17 and a second gas sensing body 18 are arranged on two pairs of electrodes 15a and 15b and 16a and 16b mounted on the top surface of an insulation substrate 14. The gas sensing body 17 is a Cu-W-Al2O3 catalyst baked on an SmO2-Nb based semiconductor film and highly sensitive to CO, tobacco smoke, alcohol and the like. The gas sensing body 18 is a Pt-Rh-Al2O3 catalyst baked on the same semiconductor film and highly sensitive to CH4, H2 and the like. A heater 19 is buried in a substrate 14 and a voltage is applied between leads 13b and 13e to heat the substrate 14. Here, when a specified gas exists in the atmospheric air, the gas sensing bodies 17 and 18 react thereto and a resistance value changes between leads 13a and 13c and 13a and 13d, thereby detecting the gas.
