Gas leak detecting device and gas leak detecting method

Abstract

A gas leak detecting method includes a test article preparation operation of preparing a test article that includes a first coupling region, in which a second component is coupled to one side of a first component, and a second coupling region, in which a third component is coupled to one side of the second component, a test article arrangement operation of arranging the test article in an inner space of a body unit, and a sealing inspection operation of examining a gas discharged from the inner space and inspecting whether or not the first coupling region or the second coupling region is sealed. In the test article arrangement operation, each of the first coupling region and the second coupling region is located inside the inner space.
