Abstract
In order to prevent cracking of a window material in manufacturing an optical measurement cell that satisfies various performances required for airtightness, heat resistance, and the like by atomic diffusion bonding, an optical measurement cell into which a sample is introduced includes a light transmission window through which light is transmitted, and includes a window material forming the light transmission window, and a flange member to which the window material is bonded via a metal thin film, and a ratio of a thermal expansion coefficient of the flange member to a thermal expansion coefficient of the window material is 0.5 times or more and 1.5 times or less.
