Abstract
In a sample cell that is sealed with an X-ray transmission sheet after a sample such as a liquid fuel or the like is contained therein, when an internal pressure is increased, a cup end surface is deformed so as to increase an internal capacity of the sample cell before the X-ray transmission sheet serving as a window part is expanded. The cup end surface is formed by folding a film-like material and, when the internal pressure of the sample cell is increased, the cup end surface is unfolded outwardly of the sample cell to increase the internal capacity of the sample cell. The increase in pressure is relieved by the increase in capacity, and the expansion of the X-ray transmission sheet is thereby prevented.
