Abstract

PURPOSE: To obtain a carbon monoxide detector which is free from decrease in detection capability even when it is used in the presence of NOx gas, by forming a platinum layer on the surface of an n-type oxide semiconductor layer via a layer of an insulating material.
CONSTITUTION: An n-type oxide semiconductor layer 2 consisting of SnO2, ZnO or the like, a layer 3 of an insulating material, such as SiO2 or Al2O3 and a platinum layer 4 are laminated in the mentioned order on an insulating base 1 to obtain a carbon monoxide detector. The platinum layer 4 is formed by sputtering or deposition to an average thickness of 0.3W30 atoms. An average thickness of the layer 3 of the insulating material may be around 20W200Å.
