Abstract: 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.
