Abstract: PURPOSE:To enable the removal of interference fringes generated by a multiplex reflection between electrode plates by providing a sample cell to hold a sample between the electrode plate comprising a semiconductor substance passing through infrared rays and the electrode plate for reflecting the infrared rays. CONSTITUTION:An electrode plate 3 of a liquid crystal cell 1 comprises a metal base (gold) mirror ground so as to reflect infrared rays completely and a polyimide oriented film 5a is applied on an internal surface. An electrode plate 7, for example, comprises Ge transmitting infrared rays and a polyimide oriented film 5b is applied on the internal surface.
