PROBLEM TO BE SOLVED: To provide a method for quantifying fine nanometer-sized precipitates and the like in a metal material by size. SOLUTION: The method for quantifying a precipitate and the like in a metal material includes: an electrolysis step of electrolyzing a metal sample in an electrolytic solution; an immersion step of immersing a remaining part of the metal sample extracted from the electrolytic solution in a dispersive solution; a separation step of filtering the precipitate and the like separated in the dispersive solution by a filter at least once; and a quantification step of quantifying a focused element content of the precipitate and the like captured by the filter. The relationship between the electrolyzed quantity and the quantified focused element content is determined by repeatedly performing the electrolysis step to the quantification step while changing the electrolyzed quantity of the metal sample in the electrolysis step. The focused element content of the precipitate and the like, when the electrolyzed quantity is extrapolated to 0, is determined to be the focused element content of the precipitate and the like having a size larger than a size defined from a filter hole size.
