Furthermore, if necessary, a pattern is formed on the surface layer by laser processing. Since the pattern of the surface layer and the pattern of the exposure of the metal layer are formed, it is possible to display a wider variety of patterns.
[0007]
Further, if necessary, the surface layer is composed of a main surface layer and a sub surface layer made of a different material provided on the main surface layer, and a pattern is provided by laser processing on at least one of the main surface layer and the sub surface layer. It has a configuration. A surface pattern composed of a main surface layer and a sub surface layer can be easily formed with a three-dimensional pattern with irregularities by laser processing, and the main surface layer under the sub surface layer can be exposed to form an effective pattern, It can be rich in decorativeness.
[0008]
Furthermore, if necessary, the surface layer has a configuration in which excavation is performed with dots and a pattern in which excavation portions having different density and depth of the dots are continuous is formed. Since the sparse density and depth of the dots are different on the surface layer composed of the main surface layer and the sub surface layer, when the sub surface layer is different in color from the main surface layer, the sub surface layer is displayed so that the color shading gradually changes. It is possible to produce a variety of patterns with even more decorativeness.
Further, if necessary, the surface layer is removed by laser processing in the non-sticking portion of the metal sheet, and the base is formed by a pattern excavated by laser processing. A pattern can be easily formed on the substrate by laser processing, and a three-dimensional pattern with deep irregularities can be formed.

The pattern M2 is a leaf portion of the tree, and is configured by exposing the green color of the metal sheet S2.
The excavation of the patterns M1 and M2 is easily performed because the laser beam with a certain irradiation energy is reflected by the portions of the metal sheets S1 and S2 and does not easily enter deeper.
[0012]
As the pattern, a pattern (m1, m2, m3, m4, m5) formed by laser processing is formed on the surface layer 11. In FIG. 1, the pattern m1 is a trunk portion of the tree, and is configured by excavating and exposing the woody portion of the main surface layer 11A. The pattern m2 is the central part of the mountain, and the woody part of the main surface layer 11A is slightly excavated and exposed.
