PROBLEM TO BE SOLVED: To provide a technology for identifying pressure in a housing space, the pressure being necessary for making a liner and a reinforcing layer tightly adhere to each other, in a high-pressure tank inspection device method.SOLUTION: The high-pressure tank inspection method is used for inspecting a high-pressure tank having a reinforcing layer having a space therein, and a liner arranged in the space and having a housing space for housing a fluid. The method comprises: a step of further supplying inspection fluid into the housing space which is in an initial state in which inspection fluid is filled into the housing space at pressure that is the same with tank inside pressure being the outside pressure of the reinforcing layer, thereby pressurizing the housing space from the initial state, and measuring a pressure increase amount in the housing space and a capacity increase amount in the housing space; and a step of estimating that, in a relationship between the pressure increase amount and the capacity increase amount, the pressure of a point at which the pressure increase amount is minimum out of potions in which the relationship becomes a linear relationship is minimum pressure for making the liner and the reinforcing layer tightly adhere to each other. |
