た。As described above, in the conventional satin finish, the recess is formed in an independent state, and the bottom of the recess is easily clogged with dirt. Once the dirt is clogged, it is difficult to remove the dirt. Was. Therefore, the corners forming the concave portions are smoothed with a chemical or the like, and processing is performed so that attached dirt is easily removed. However, a sufficient effect is obtained only by increasing the number of processing steps. I could not do it. Further, since the convex portion (reference surface) is wider than the concave portion, there has been a problem that a scratch such as a nail scratch is easily formed.
