摘要： PROBLEM TO BE SOLVED: To provide a gas alarm for inspecting the working of a city gas detecting function by a simple method even if a tap for city gas is in an unopened state.
SOLUTION: This gas alarm comprising a film-like gas sensitive layer 26 made of tin oxide, sets the temperature of the sensitive layer so that it is periodically switched between a low temperature and a high temperature, and detects an electric resistance value of the sensitive layer to determine whether an alarm is to be generated. A normal detection mode is provided in which an electric resistance value of the sensitive layer is detected when it is kept at a high temperature thereby detecting city gas, and an inspection mode in which inspection is performed on the working of an alarm function. In the inspection mode, the electric resistance value of the sensitive layer is detected when it is kept at a high temperature. A detection period for an electric resistance value after the switching to the high temperature in the inspection mode is set to be shorter than a detection period for an electric resistance value after the switching to the high temperature in the normal detection mode.
