Abstract
PURPOSE: To excel in sensitivity and elongate he durable life showing stable sensitivity for a long period, by separating the oxide semiconductor of which electric resistance changes according to adsorption and desorption of halogen gas and the catalyst layer active to halogen gas in a single state respectively.
CONSTITUTION: A pair of semicylindrical electrodes 3a, 3b are provided on the outer circumference of a cylindrical insulation base body 1 in which a coil heater 2 is suspended inside. An oxide semiconductor 4 is formed on the surface of the base body 1 containing the electrodes 3a, 3b. And a porous diaphragm 7 is provided further on the circumference, and a catalyst layer 5 carrying catalyst is provided on the surface thereof. Two lead wires each, 6a, 6a, 6b, 6b, and connected to the electrodes 3a, 3b, respectively.
