摘要： PROBLEM TO BE SOLVED: To provide a fire detecting device for accurately detecting a fire in the initial stage. SOLUTION: In a fire preferred embodiment, a fire is detected by detecting a unique humidity change pattern in which the humidity temporarily rises and then, drops in the initial stage of a fire. In a second preferred embodiment, a contact combustion type gas sensor 40 attached at a gas leak alarm is used as a fire detecting element. This contact combustion type gas sensor 40 is driven by being heated by being electrically energized, and a fire is detected by detecting a sensor output change pattern unique to a sensor output of the initial stage of a fire from sensor output time series data obtained from a sensor output of a specific point of time during a rising period till the sensor output after electrically energized is stabled. By this, fire in the initial stage which has been difficult to be detected can be accurately detected.
