摘要： PURPOSE:To obtain a gaseous component detecting element which has good sensitivity, high response speed and large joint strength to a substrate and is free from exfoliation, etc. by using a sintered body of a specific metallic oxide as the sintered body of the metallic oxide whose the resistance value changes with the components of gas to be detected. CONSTITUTION:The gas detecting element 1 is constituted by providing a pair of electrodes (platinum) 4, 5 on the substrate internally contg. a heating element 2 and laminating the metallic oxide 6 thereon. The sintered body of the metallic oxide contg. >=1 kinds of metallic oxides such as Er2O3, Sm2O3 and In2O3 which consist essentially of titanium dioxide and difficulty cause a solid phase reaction with titanium dioxide and >=1 kinds of noble metals among platinum elements is used for the sintered body 6 of the metallic oxide. The increase in denseness is not accelerated and the flowability of the gas is maintained even if the metallic oxide is calcined at a high temp.; therefore, the responsiveness is improved. Since the calcination at the high temp. is possible, the joint strength to the substrate is high enough to obviate the generation of exfoliation, etc.

摘要： PURPOSE:To obtain a detection element enhanced in gas response and hardly generating release at the time of use, by using titanium dioxide and metal oxide as a baked body. CONSTITUTION:A gaseous component detection element 1 is formed by a method wherein a pair of platinum electrodes 4, 5 are provided on an aluminum substrate 3 having an unbaked heat generator 2 mounted therein and metal oxide 6 based on titanium dioxide and containing one or more of rare earth element oxide and high m.p. metal oxide is laminated onto said electrodes 4, 5. In thus formed gaseous component detection element wherein Er2O3, Sm2O3 and Ir2O3 are respectively added to the metal oxide 6, a response time, when the gaseous component in gas to be inspected changes from a rich atmosphere to a lean atmosphere, becomes short.
