Abstract

PURPOSE: To provide a combustible gas detection element with a proper element resistance value, a sufficient gas sensitivity and a high dependency on concentration by empolying In2O3 and HfO2 or chromium oxide for effective components while In2O3 is used as main material.
CONSTITUTION: In2O3 and HfO2 or chromium oxide are employed as effective comnents. A raw material powder is produced by blending and mixing in the manner that the rate of HfO2 or a chromium oxide existing within the effective component is 1W50wt% (wherein chromium oxide is expressed in terms of Cr2O3). Said material powder is formed into a cylindrical body 2 having the platinum electrode 1 imbedded thereinto and sintered to make a combustible gas detection element 3.
