Abstract
A precipitate and/or an inclusion in a metal material are extracted by electrolysis using an electrolyte solution. The electrolyte solution contains an adsorbent physically adsorbed and/or chemically adsorbed to any metal other than a matrix metal of the metal material. The extracted precipitate and/or inclusion can be quantitatively analyzed with high accuracy.
