Abstract
A metal mask is used in applying a printing material to an object to be printed by the sliding of a squeegee across a first surface of the metal mask. The metal mask has a plurality of openings extending from the first surface to a second surface facing the object. The metal mask has a bridge section and a filling section. The bridge section is disposed between first and second openings, and is recessed from the second surface. The filling section is provided on the second surface-side of the bridge section for being filled with printing material. The filling section communicates with the respective ends of the first and second openings. When viewed from the second surface, the filling section has a width that is larger than a width of the openings in a direction that intersects with a direction extending between the first and second openings.
