Abstract: The metal mask has a body having a first surface in contact with a surface of a workpiece, a second surface opposite the first surface and a third surface between the first surface and the second surface, and an eave portion continuous with the body portion and projecting outwards from the first surface, the eave portion being arranged away from the surface of the workpiece. The third surface (side surface) of the body portion of the metal mask may have a stepped portion formed of the eave portion. The third surface (side surface) of the body part has an inclined surface that extends from the first surface to the second surface and may have a structure in which the eave portion is arranged above the inclined surface.
