PURPOSE: A method for preprocessing a polymer sample for an analysis using an electron microscope is provided to specifically analyze a composition distribution of vehicle parts in which a polymer composite and a nylon system polymer composite material are applied and to obtain an excellent effect for select-dying a nylon ingredient. CONSTITUTION: A method for preprocessing a polymer sample for an analysis using an electron microscope is as follows. A low temperature wet ultra-thin sectioning method is implemented. Phosphotungstic acid hydrate solution is processed on a sample. The distilled water is dropped on the dyed sample.
