Abstract
An n-type semiconductor gas detecting element. The semiconductor oxide is bismuth molybdate having the composition Bi.sub.2 O.sub.3.3MoO.sub.3 and the gas detecting element formed therewith has high sensitivity to combustible gas. The detection of the combustible gases is based upon the change of electrical conductivity of a thick film of the semiconductor oxide detecting element resulting from the combustible gas component in an oxygen-containing atmosphere.
