Abstract

Disclosed is a method for prediction of a film material such as a raw material for organic EL. In the method, a film material having an evaporation rate (V(%)) represented by the formula below can be predicted based on the values of the constant (Ko) and the activation energy (Ea). V=(Ko/P)×ewherein Ko represents a constant (%·Torr), P represents a pressure (Torr), Ea represents an activation energy (eV), k represents a Boltzmann constant, and T represents an absolute temperature.
