PURPOSE: To obtain a bamboo plywood by combining a plate material made of a split material obtained by splitting a green bamboo into small pieces without occurrence of distortion or warpage.

CONSTITUTION: A green bamboo is cut to a predetermined length so that each cut part has a plurality of nodes. The cut green bamboo is peripherally splitted into a plurality of split materials. A large number of plate materials 24 each obtained by processing the split material into a plate are overlapped to form an intermediate plywood 34. A sheet 34A is formed by stripping the intermediate plywood 34 vertically to the overlapped surface thereof. A bamboo plywood 40 is obtained by a method in which a large number of sheets 34A are vertically laminated and bonded in three or four layers so as to cross each other with respect to the grain direction thereof.
