PROBLEM TO BE SOLVED: To provide a method for quickly and reliably inspecting leak in a heat pipe regardless of the shape of the heat pipe and the type of hydraulic fluid, and also to provide an inspecting apparatus for the method. SOLUTION: The heat pipe 1 is put into an inspection chamber 2, the inside of the inspecting chamber 2 is evacuated, the gas of the hydraulic fluid leaking out of the heat pipe 1 into the inspection chamber 2 is analyzed by a mass spectrometer 4, and the leak in the heat pipe 1 is inspected, thus analyzing and inspecting the hydraulic fluid gas leaking out of the leaked place of the heat pipe 1 by the mass spectrometer, and hence quickly, reliably performing inspection without depending on the type of hydraulic fluid. Additionally, the difference between internal and external pressures of the heat pipe in inspection is small, thus preventing the deformation of the heat pipe during the inspection. A reserve chamber is arranged in contact with the inspection chamber 2, and water on the surface of the heat pipe is removed in the reserve chamber, thus shortening evacuation time in the inspection chamber 2.
