Embodiments of the present invention shown in the drawings will be described below. First, the ceramic decorative plate 1 used in the present invention shown in FIGS. 1 to 4 will be described.

In this ceramic decorative plate 1, first, a half layer of a granular inorganic molding material composed of glass cullet, aluminum oxide, bentonite and a coloring agent (metal oxide) is filled in a mold of a press molding machine, Then, after setting the metal wire 2 thereon as shown in FIG. 1, the remaining molding material of the same quality as above is charged into the mold from above,
Pressurized at ~ 500 kg / cm ² to form a plate (Fig. 2
reference). After this molding, this is baked in a baking furnace such as a roller hearth kiln at a temperature of 800 ° C. for 2 to 5 hours. After baking, the surface 1a side which is the decorative surface is polished or left as it is, and the decorative plate 1 is completed. Further, the decorative plate 1 is a square or rectangular 1 having a predetermined length and width.
Use a single plate.

As the metal wire 2 made of the stainless wire described above, the metal wire 2 is arranged in a lattice form as shown in FIG.
The metal wire 2 is intended to prevent the falling of fragments when the decorative plate 1 is damaged, and has a wire diameter of 0.3 mm, for example.
A stainless wire such as SUS304L having a low carbon content of up to 1.6 mm is used, and particularly, the plate thickness is 5 mm to 20 m.
In the case of making a decorative plate of m, the wire diameter is in the range of 0.3 mm to 0.9 mm in consideration of the shrinking action (shrinkage rate) during firing of the inorganic molding material or the cutting work by a cutter after firing. A relatively small diameter is used.

The metal wire 2 has a continuous sinusoidal shape as shown in FIG. 3, and the relationship between the wave height h and the period t is h = 2 when the wire diameter is 0.6 mm. .7 m
m and t = 5.2 mm.
