Method for manufacturing vapor deposition mask, metal plate used for producing vapor deposition mask, and vapor deposition mask

摘要

PROBLEM TO BE SOLVED: To provide a metal plate capable of providing stably a resist pattern having a narrow width on a first surface or on a second surface.SOLUTION: A metal plate used for producing a vapor deposition mask includes a body layer comprising an iron alloy containing nickel, and at least one surface layer comprising copper or a copper alloy. At least one of a first surface and a second surface of the metal plate is constituted of the surface layer.SELECTED DRAWING: Figure 10
