Provided is a method for evaluating a polymer material whereby the dispersion state of a filler in the polymer material can be quickly and quantitatively evaluated.nA method for evaluating a polymer material, said polymer material comprising a polymer compound and a filler and having a smooth surface at least as the top surface thereof. By use of a focused ion beam (FIB) (10), the polymer material (1) is cut along a direction at an angle (α) of 1-60 o relative to the surface of the polymer material. Then, an image of the smooth surface (1A) of the polymer material, said smooth surface (1A) having been formed by the cutting, is taken from a direction perpendicular to the smooth surface. |
