PROBLEM TO BE SOLVED: To provide a method for evaluating a resin molding, capable of observing the fracture surface or surface of a resin molding with a large magnification in spite of types of resin and accurately performing fracture surface analysis by SEM and surface evaluation analysis by chemical composition analysis in the same observation part of the same resin molding.SOLUTION: The method for evaluating a resin molding comprises: the surface observation step of observing the surface of the resin molding having vapor-deposited metal osmium with a scanning electron microscope; and the Raman spectroscopic analysis step of Raman-spectroscopically analyzing the same observation part of the resin molding. The thickness of the metal osmium film on the fracture surface or surface of the resin molding is preferably 0.2 nm or more and 10 nm or less. The fracture surface or surface of the resin molding can be observed with a large magnification in spite of types of resin molding, and chemical composition analysis on the same fracture surface or surface as observed can be accurately grasped.SELECTED DRAWING: Figure 2 |
