An optical function portion is provided on one surface of the movable portion and a rib portion is provided on the other surface of the movable portion. The rib portion includes eight extending portions of first to eighth extending portions. When setting directions in which the first to eighth extending portions extend as first to eighth extending directions respectively, and setting an angle between the first and second extending directions as a first angle, an angle between the third and fourth extending directions as a second angle, an angle between the fifth and sixth extending directions as a third angle, and an angle between the seventh and eighth extending directions as a fourth angle, each of the first and second angle is larger than each of the third and fourth angle.

摘要： A dispersion stability evaluation method is a method for evaluating a dispersion stability of dispersoid dispersed in a dispersion medium. The dispersion stability evaluation method includes a first step of holding a sample including the dispersion medium and the dispersoid on a reflective surface, and a second step of causing terahertz waves to be incident on the reflective surface from a side opposite to the sample and detecting the terahertz waves reflected by the reflective surface. In the second step, while a state where the dispersoid are allowed to move toward the reflective surface is maintained, a plurality of detection results respectively corresponding to a plurality of times apart from each other are acquired.
