A method for manufacturing a vapor deposition mask and a method for manufacturing a metal plate used for manufacturing a vapor deposition mask.

摘要

PROBLEM TO BE SOLVED: To manufacture a thin-film deposition mask having a small variation in the shape of a through hole. SOLUTION: A method for manufacturing a vapor deposition mask is made of an iron alloy containing nickel, and a first surface located on the substrate side to which a vapor deposition material that has passed through a through hole adheres and a second surface located on the opposite side of the first surface. A preparatory step for preparing a metal plate including a surface, a surface layer removing step for removing at least the surface layer on the first surface side of the metal plate, and a processing step for etching the metal plate to form a through hole in the metal plate.
