Abstract
The present invention relates to a method for producing a deposition mask having a structure in which a metal mask sheet with a plurality of opening patterns formed is disposed under tension on and fixed to a metal frame, the method including: a first step of bonding a peripheral part of the metal mask sheet to a synthetic fiber mesh to which constant tension is applied; a second step of cutting off a part of the mesh corresponding to a deposition effective region with a size capable of arranging therein the plurality of opening patterns of the metal mask sheet; a third step of connecting and fixing the frame to the peripheral part of the metal mask sheet on an opposite side to the mesh; and a fourth step of removing the mesh from the metal mask sheet.
