PROBLEM TO BE SOLVED: To provide a corrosion method using a corrosive liquid, capable of accurately and microscopically detecting a texture surface of the metal texture of martensite stainless steel or alloy tool steel, when the metal texture of the martensite stainless steel or alloy tool steel is investigated microscopically. SOLUTION: In the microscopic detection method of the metal texture of the martensite stainless steel or alloy tool steel, the martensite stainless steel or alloy tool steel is corroded by a corrosive liquid composed of 3-7 ml of HCl, 0.5-1.5 gr of picric acid, 100 ml of an alcohol and 7-13 ml of a surfactant, in order to observe the metal textrure of the martensite stainless steel or alloy tool steel.
