Abstract
PURPOSE: To obtain an element of superior selectivity to specific gas by providing multilayers of mutually different catalyst layers selected from the groups of Pt, Pd, Ph on the surface of the sensitive body.
CONSTITUTION: A gas sensitive body 4 including a pair of electrodes 3a, 3b is covered on the surface of a cylindrical insulation substrate 2 and further catalyst layers 5, 6 selected from Pt, Pd, Rh are so provided on the gas sensitive body 4 surface as to assume a two layer structure. In addition, the gas sensitive element 1 is hung by means of the lead wires 9 connected to the terminals 8 provided to a substrate 10. A heater 7 is provided in the hollow part of the cylindrical substrate 2. Provision of the catalyst layers in multilayers in this way makes it possible to detect only the specific gas and to obtain the gas sensitive element of superior selectivity.
