ABSTRACT:
A gas sensor assembly comprises first and second sinters each composed of a metal oxide having an electric resistance value varying in dependence on the composition of a detected gas as well as the detected gas temperature, and the first sinter has deposited thereon a catalyst for causing an oxidation reaction of the detected gas components. To detect a change in the electric resistance value of the first sinter which is temperature compensated by the second sinter, the first and second sinters are connected to each other with separated first and second electrodes so as to support the sinters in an opposing relation and a third electrode is connected to the second electrode in such a manner that the third electrode is apart from the first and second electrodes.
