1. An optical measurement cell having translucent windows through which light is transmitted and into an interior of which is introduced a test sample, comprising:
a planar window material that forms the translucent windows;
a join supporting portion that is joined to an outer edge portion of a main surface of the window material and supports the window material; and
a low thermal expansion component that is provided on an outer-side circumferential surface of the join supporting portion and whose coefficient of thermal expansion is lower than a coefficient of thermal expansion of the join supporting portion, so as to reduce a thermal stress generated in a join portion between the window material and the join supporting portion.
