Abstract

PURPOSE: To improve the performance of response and the durability of the device by providing a specific heater that heats a gas sensor.
CONSTITUTION: A bulky self-exothermic element (resistance element), which is made of a complex of conductive ceramics, metallic resistor, noble metals such as Ag, Pd and Pt and heat-resisting oxides such as Al2O3, ZrO2 or the like, is used for the gas sensor heater 3, and the film-shaped gas sensor 1 the main component of which is a metal oxide semiconductor such as SnO2 and ZnO is joined with said heater 3 directly or through the insulating layer. When the gas sensor heater 3 is energized through the lead wires 6', 7', the gas sensor 1 is heated, and when a combustible gas is adsorbed to the heated gas sensor 1, resistance of the gas sensor 1 is changed and the gas is detected by detecting the resistance change by means of the electrodes 8, 6, 7. With the specific gas sensor heater 3 and the gas sensor 1 joined with the heater 3, the heat transfer to the gas sensor can be improved and the deterioration of the gas sensor can be reduced.
