It is preferred to have a surface pattern composed of multiple tones.

Conventionally, a composite metal plate manufactured as follows has been used for manufacturing accessories, ornaments and various crafts having such a surface pattern. That is, as shown in FIG. 4, the holes 1 having a predetermined shape are formed at predetermined positions of the plurality of metal plates 1.
After a is machined by cutting or the like, these metal plates 1 are overlapped so that the holes 1a are overlapped with each other to form a laminate 2, which has a color tone different from that of the metal plate 1, and After inserting a metal rod 3 having the same shape as the inside of the hole 1a into the hole 1a, the metal plate 1 and the metal rod 3 are integrally joined to each other by diffusion welding to form a metal composite. Then, the metal composite is cut into a plate shape to obtain a composite metal plate.

[0004]

However, in the conventional method for manufacturing a composite metal plate, the metal rod 3 is inserted into the hole 1a formed in the metal plate 1 by machining. Also, there is a problem that it takes time to process the metal rod 3 into a predetermined shape. Further, due to the precision of machining, the inner surface of the hole 1a of the metal plate 1 and the metal rod 3 are
There is a problem that a gap may be formed between the outer surface and the outer surface, and this gap causes defects in diffusion bonding, and the produced composite metal plate has a poor appearance. Moreover, since the hole 1a is machined, it is extremely difficult to machine it into a complicated shape such as a star or a flower, and only a simple pattern can be formed on the composite metal plate. The value was unavoidable.

The present invention has been made in view of the above circumstances, and it is possible to significantly shorten the processing time, prevent the formation of gaps between patterns, and form a complex metal plate and a composite metal plate thereof. It is intended to provide a manufacturing method.
