PROBLEM TO BE SOLVED: To provide an observation method for a polymer material including an inorganic filler, which facilitates interpretation of a dispersion state of the inorganic filler in the polymer material.;SOLUTION: When analyzing a phase separation structure of the polymer material where at least two or more kinds of polymeric materials and one or more kinds of inorganic fillers are mixed as raw materials, a sample piece of the polymer material is immersed in an electron staining solution which chemically reacts with the inorganic fillers and with at least one or more kinds of the polymeric materials to form a heavy metal compound. The sample piece is then washed with water and observed by a scanning electron microscope to capture a reflected electron image where the polymeric materials having reacted with the solution, the polymeric materials not having reacted with the solution, and the inorganic fillers are dispersed. Then, a reflected electron image is obtained such that brightness of portions of pores where the inorganic fillers are eluted and brightness of portions where the inorganic fillers are not eluted are equalized to each other in the captured reflected electron image.;COPYRIGHT: (C)2012,JPO&INPIT
