摘要： PROBLEM TO BE SOLVED: To reduce a waiting time due to fatigue of a gas sensor. SOLUTION: In a leak detector, specimen gas and background gas are alternately supplied to first and second gas sensors, and the gas flow rates of the specimen gas and the background gas are set to be constant and to be equal to each other. When gas leakage is detected from an output of the gas sensor contacting with the specimen gas, and the output of the gas sensor is equal to or exceeds a threshold for a prescribed time or longer continuously, flow passages of the specimen gas and the background gas are switched.
