Abstract
There is provided a gas sensor fault detection device that detects a sensor fault in a gas leak inspection device. The gas sensor fault detection device includes: a gas blowing unit that blows a gas toward a detection area of a gas sensor of the gas leak inspection device; and a position fixing unit that fixes a position of the gas blowing unit with reference to a hypothetical gas leak position of an inspection target being inspected by the gas leak inspection device.
