Disclosed is a method for analyzing a metallic material, which comprises the following steps: an electrolysis step of electrolyzing a metal sample in an electrolysis solution; a step of removing the metal sample from the electrolysis solution after the electrolysis is completed; a separation step of immersing the metal sample removed from the electrolysis solution in a dispersing solution which is different from the electrolyte solution and has dispersibility, thereby isolating at least one member selected from the group consisting of a precipitate and an intervening material adhered to the metal sample; and an analysis step of analyzing at least one member selected from the group consisting of the precipitate and the intervening material extracted in the dispersing solution.
