PROBLEM TO BE SOLVED: To provide a manufacturing method of shadow mask never causing a diameter failure of pore by forming an etching corrosion-resisting resin layer without leaving bubbles in a pore in the formation of the etching corrosion- resisting resin layer on the pore side in the manufacturing method of a shadow mask by photeteching. SOLUTION: The metal surface within the pore is subjected to a surface treatment with plasma to form a micro rough surface 40, and an etching corrosion-resisting resin is applied to form the etching corrosion-resisting resin layer 47. Otherwise, the metal surface within the pore is subjected to a surface treatment by electrolysis to form the micro rough surface 40, and the etching corrosion-resisting resin is applied to form the etching corrosion-resisting resin layer 47.
