A water vapor concentration in a test gas in a first space of a measurement space in which a sample is disposed is adjusted, and a water vapor concentration m a earlier gas in a second space separated from the first space by the sample is measured by a measurement unit. When the water vapor concentration in the test gas is changed, a shift B in charge of the water vapor concentration in the carrier gas from the change of the water vapor concentration in the test gas is calculated. The calculated shift B in the change of the water vapor concentration in the carrier gas corresponds to ease of moisture accumulation in the sample. Thus, it is possible to analyze not only the amount of moisture permeating the sample but also the ease of moisture accumulation, so that characteristics of the sample can be widely analyzed.

A one-side-protected polarizing film having a transparent protective film on only one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin, has a thickness of 10 &#x3bc;m or less, and is designed to have a single-body transmittance T and a polarization degree P representing optical properties satisfying the condition of the following formula: P&#x3e;&#x2212;(10&#x2212;1)&#xd7;100 (provided that T&#x3c;42.3) or P&#x2265;99.9 (provided that T&#x2265;42.3); and the other surface of the polarizer has a transparent layer thereon satisfying formula 1 (F&#x2265;3) and formula 2 (C&#x2265;e), given that the thickness thereof is F (&#x3bc;m) and the compressive elastic modulus thereof at 80&#xb0; C. is C (GPa). Even when the polarizer has prescribed optical properties and the thickness is 10 &#x3bc;m or less, this one-side-protected polarizing film is capable of suppressing through cracks and nano-slits.
