PROBLEM TO BE SOLVED: To provide a method for evaluating a fine particle dispersion state in a non-aqueous paint, capable of evaluating a fine particle dispersion state, and establishing optimal dispersion conditions. SOLUTION: The method comprises the measuring step of using an additive-containing paint as a sample to be measured and measuring the zeta potential of the sample, the evaluating step of evaluating the dispersion of the paint by estimating the adsorption state of the additive based on the zeta potential measured in the measuring step, and the dispersion condition deciding step of setting the zeta potential when the dispersion is evaluated to be good in the evaluating step as a target value, and deciding conditions regarding fine particle dispersion in which the zeta potential becomes the target value.
