Abstract

PURPOSE:To make the titled element difficult to receive the effect of humidity and enhance concn. separability by using In2O3 as a main component, Sm2O3 as the 1st subcomponent, and specific oxides selected from transition metals and rare earth metals as the 2nd subcomponent. CONSTITUTION:In2O3 is used as a main component, Sm2O3 as the 1st subcomponent, and further >= kinds of oxides selected from the group consisting of Nb2O5, HfO2, Cr2O3, NiO, La2O3, Sc2O3 and Y2O3 are used as the 2nd subcomponent and as effective component, these component powders are mixed, and the mixture is calcined to obtain a sintered body which is used as an inflammable gas detecting element. At this time, the amounts of the respective components are set at 90- 35wt% the main component, 5-35wt% the 1st subcomponent, and 5-30wt% the 2nd subcomponent. Thereby, the effect of humidity is prevented by the 1st subcomponent, and concn. separability is improved by the 2nd subcomponent.
