題もあった。However, according to the conventional screen 1 as shown in FIG. 4, the first portion 1a
A step portion 1c is formed at a boundary between the second portion 1b and the second portion 1b. Therefore, when printing, the squeeze 3 will be changed to the step portion 1 as shown in FIG.
When getting over c, there was a problem that the squeeze 3 was worn and the life was shortened. Further, since etching is performed to form the second portion 1b having a small thickness, in particular, in order to provide a portion having a plate thickness of three or more, there are many cases such as resist coating, exposure, development, etching, and peeling. There was also the problem that the process had to be repeated and the cost increased.
