Zusammenfassung:	To provide a method and a device for evaluating surface roughening treatment on a metallic surface, capable of easily and suitably evaluating surface roughening treatment on a metallic surface.SOLUTION: A method includes steps for: acquiring image data of a surface of an inspection object which has been subjected to surface roughening treatment (S2); calculating an NDSI value of each pixel of the image data, regarding two wavelengths of light selected in advance, on the basis of the image data (S7); and evaluating surface roughening treatment for the inspection object on the basis of the NDSI value (S8-S12).SELECTED DRAWING: Figure 5 【課題】金属表面の粗面処理を簡便且つ好適に評価し得る金属表面の粗面処理の評価方法および評価装置を提供する。【解決手段】粗面処理を施された検査対象の表面の画像データを取得するステップＳ２と、前記画像データに基づき、予め選定された２つの波長の光に関し、前記画像データの各ピクセルにおけるＮＤＳＩ値を算出するステップＳ７と、前記ＮＤＳＩ値に基づき、検査対象の粗面処理に関する評価を行うステップＳ８～Ｓ１２とを実行する。【選択図】図５
