Abstract: A gas detector includes a gas detection element having a protection layer formed of an oxide film mainly containing tantalum oxide (Ta2O5). Since the protection layer has excellent condensed-water resistance, even when water droplets adhere thereto, the morphology thereof does not change from dense to porous. Thus, since a change in property of the protection layer, which would otherwise be caused by adhesion of water droplets, can be reduced in the gas detector, even when water droplets adhere to the outermost surface layer of the gas detection element, impurities can be prevented from entering the protection layer (the outermost surface layer), whereby a change in thermal capacity of the gas detection element can be reduced. Thus, the gas detection element of the gas detector has excellent alkali resistance and condensed-water resistance.

Abstract: A fluid state detection apparatus which can detect a short failure in which a constituent Wheatstone bridge circuit is shorted to a power supply. A combustible gas detection apparatus (1) judges that a short failure has occurred in a constant temperature control circuit (231) (S240) when a top potential V21 is equal to or greater than a first judgment value Vth1 and a difference D1 (=V11?V31) is equal to or greater than a second judgment value Vth2. As a result, apparatus (1) can distinguish “a state in which a bridge circuit (210) is shorted to a DC power supply (40) (where the constant temperature control circuit 231 is in a short failure state)” from “a state in which the resistance of the heat generation resistor (15) deceases due to a combustible gas (hydrogen)” based on the top potential V21 and the difference D1.
