In the method for analyzing an impurity of an iron-based powder according to an embodiment, an iron-based powder produced by a spraying method is collected from a molten steel having a predetermined composition. The iron-based powder is immersed in an acidic solution, and a metal component in the iron-based powder is dissolved in the acidic solution. The components remaining in the iron-based powder that are not dissolved in the acidic solution are extracted. And the weight of the extracted non-dissolved component is measured. |
