摘要

This method for producing a deposition mask comprises steps of: preparing a deposition mask preparation body having a metal mask on one surface of a resin plate for a resin mask and a protective sheet on the other surface of the resin plate, the protective sheet having a peel strength as determined in accordance with JIS Z-0237:2009 of 0.0004 N/10 mm (inclusive) to 0.2 N/10 mm (exclusive); irradiating the resin plate of the deposition mask preparation body with laser light from the metal mask side to form resin mask openings corresponding to a pattern to be formed on the resin plate by deposition; and removing the protective sheet from the resin mask with the resin mask openings corresponding to the pattern to be formed by deposition.
