Реферат: In this invention, amounts of gas permeation for each of a plurality of rubber sealing components that have been manufactured according to the same specifications are measured through helium leak testing and sample data is acquired in which for each sealing component, the measured value at a reference time CT during an unstable period A when the transmission amount was rising and the measured value in a stable period B when the transmission amount was stable are paired (sample acquisition). The plurality of acquired pairs of sample data are used to define the relationship between the measured value at the reference time CT and the measured value in the stable period as a linear function (function definition). Amounts of gas permeation of a sealing component to be inspected that has been manufactured according to the same specifications as the sealing components are measured through helium leak testing, and the defined linear function is used to estimate the value that would be measured for the sealing component to be inspected in the stable period B on the basis of measured values for the sealing component in the unstable period A (leak amount estimation).
