A manufacturing method for a vapor deposition mask used to vapor-deposit a vapor-deposition layer on each of pixels of a vapor deposited substrate provided with a plurality of active regions on which the pixels contributing to displaying are arranged, the method comprising:
- a vapor-deposition-hole forming step for forming a plurality of vapor deposition holes in a mask sheet to provide a valid portion for each of the plurality of active regions;
- and
- a covering-portion forming step for forming, outside of a shape of the valid portion corresponding to a shape of each of the plurality of active regions in the valid portion, a covering portion configured to cover a portion of the plurality of vapor deposition holes, to provide a first region having a shape corresponding to a shape of each of the plurality of active regions and to provide a second region provided with the covering portion,
- wherein the covering-portion forming step includes
- an application step for applying a covering material to a region located on the mask sheet and being to be the second region, and
- a curing step for curing the covering material applied at the application step to form the covering portion.
