It is set up. This unit decorative edge board 3 is constructed with the end surfaces of the unit decorative edges 6, the end surfaces of the unit inner decorative edges 10, and the oblique sides of the unit plate-shaped bodies 7 in contact with each other, respectively, and the decorative edge ceiling board A in FIG. Similarly, by fixing a ceiling board to the back surface of the ceiling board, they are connected to form a decorative edge ceiling board A.

Since the decorative edge ceiling board according to the first invention is configured as described above, there is no need for tight assembly of the decorative edge 1 and the plate-shaped body 2 arranged around the entire circumference as in the conventional case.
It is simple in structure and easy to assemble.

Next, the second invention will be explained. The present invention relates to a method for manufacturing a decorative edge ceiling board A having the above structure. This manufacturing method will be explained for the decorative edge ceiling board A shown in FIGS. 1 and 2. As shown in the plan view of FIG. 4 and the cross-sectional view of FIG. This is obtained by applying an adhesive to this, laminating multiple layers of adhesive-coated plates, and sandwiching this between an upper mold and a lower mold and press-molding it. Note that suitable adhesives include melamine-urea resin, phenol resin, and epoxy resin.

From the elongated plate 11 obtained in this manner, a right-angled isosceles triangle having equal lengths on hypotenuses 5 and 5 sandwiching the base 4 is cut, as shown by the broken line in FIG. 4. In that case, the unit decorative edge plates 3 whose base sides 4 are formed by the decorative concave stripes 12 on one side of the elongated plate 11 and whose base portions are the unit decorative edges 6 are arranged in alternate directions (that is, the base portions are cut out into multiple pieces so that they are on alternate sides of the long board 11). The right-angled isosceles triangular unit decorative edge board 3 has the advantage that it can be manufactured by cutting the elongated board 11 continuously and without waste.

In addition, the decorative edge ceiling board A shown in FIG. 3 has a pair of opposing lower base sides 4 and upper base sides 4' of different lengths being parallel, as shown by broken lines in FIG.
