PROBLEM TO BE SOLVED: To provide a gas leak inspection method and a gas leak inspection device capable of performing simply and surely a leak inspection in completion test or safety inspection of gas piping. SOLUTION: First of all, the interval between a pipeline opening/closing part 6c provided in the middle of a main gas pipeline having a prescribed gas pressure and a gas consumption facility 4 is set in the closed pipeline state. Then, a test gas pipeline 5e is connected to the pipeline opening/closing part 6c to thereby communicate the test gas pipeline 5e with the main gas pipeline 5c, and then the interval between the other end of the test gas pipeline 5e and the gas consumption facility 4 is set in the closed pipeline state. Then, the gas flow rate in the middle of the test gas pipeline 5e is measured, and the measurement result is outputted. The gas leak inspection can be performed simply and surely by this method, and the time required for the gas leak inspection is greatly shortened. COPYRIGHT: (C)2003,JPO
