摘要： Provided is a catalytic combustion typed gas sensor of detecting a combustible gas having a concentration equal to or more than a predetermined value based on a raised electric resistance. Herein, combustion heat generated when a combustible gas contacts to a catalytic metal (or detection element) heated by passing electric current therethrough raises a temperature and electric resistance of the catalytic metal. The electric current is made to pass through the catalytic metal such that the temperature of the catalytic metal becomes a standby temperature which is calculated by subtracting the raised temperature portion from a desorption temperature. The combustion heat is generated when the combustible gas contacts to the catalytic metal. Note the catalytic metal adsorbs a silicone compound via a silicon (Si) poisoning process and then desorbs the resulting adsorbed silicone compound at the desorption temperature. The desorption temperature is set in the range over 350° C. to 600° C.
