<p>A method for analyzing a metal material includes an electrolysis step of electrolyzing a metal sample in an electrolytic solution, an immersion step of immersing a remaining portion of the metal sample taken out of the electrolytic solution in a dispersible solution for the purpose of separating at least one substance selected from the group consisting of precipitates and inclusions attached to the remaining portion of the metal sample, a fractionation step of filtering the dispersible solution containing the at least one separated substance through filters having straight pores and a porosity of 4% or more to obtain residues trapped on the filters and filtrates, and an analysis step of analyzing at least one of the residues and the filtrates. The straight pores are filter pores which have a certain aperture shape and which extend through surfaces of the filters.</p> |
