A screen frame of a screen mask has a lower surface (third surface), a screen-mesh holding unit which holds a screen mesh, a surface (fourth surface) which is different from the lower surface, and a screen-frame fixing unit which is fixed in a state in which a first contact region which is a part or the entirety of the surface is in contact with a screen-frame holder of a printing device. The position of the first contact region in a cross section of the screen frame cut from the upper surface toward the lower surface is present above the lower surface.
