て、第１発明の同様の作用が営まれる。In the first invention of the present application, a mask plate having a large number of apertures arranged in a rectangular area surrounded by two long sides and two short sides is welded to four sides of a rectangular frame. When the mask plate is stretched, a large number of slits are formed in each outer region of the two long sides of the rectangular region of the mask plate, and even if each outer region of the two long sides is sandwiched by two pairs of clips, Although a tensile force acts in the vertical direction, the mask plate can be uniformly tensioned in the direction parallel to the long side without being disturbed by being held, and each of the two short sides of the rectangular area of the mask plate can be applied. A large number of slits are provided in the outer region, and even if the two short side outer regions are sandwiched by two pairs of clips, tensile force acts in the direction perpendicular to the short side, but narrow in the direction parallel to the short side. It is possible to apply a uniform tension to the mask plate without being disturbed by holding. Then, the mask plate that has undergone both steps at the same time has a uniform plate surface without being affected by the gripping margin of the clip. Then, since the mask plate in such a state that the plate surface is uniformly stretched is welded to the frame, the mask plate is stretched around the four sides of the frame with a uniform force distribution without disturbance. The fourth invention of the present application is the same as the first invention in the method of stretching a perforated metal thin plate.
