ー処理しておくことが望ましい。The thin plate 3 to be inserted may be a thermosetting plastic plate, a metal plate, a ceramic plate, or the like. The plastic plate or artificial marble containing the same kind of resin as the compound 41 for artificial marble is used. When a plate is used, it is particularly convenient because it has excellent adhesion and the same physical properties. Further, the thickness of the plate-like material 3 to be inserted is at least thinner than the thickness of the artificial marble to be molded, and generally, the thickness of about 1/2 to 1/5 is preferable because it is easy to integrally mold. Further, since these plate-like materials 3 are intended to improve the design, it is necessary to select the shape, color tone, and pattern in consideration of the design. When a stainless steel plate or an aluminum plate is selected as the plate-shaped material 3, it is desirable to preliminarily subject the surface to a primer treatment in order to improve the adhesion to the compound 41 for artificial marble.
