Description of the Related Art Conventionally, in fittings such as indoor doors, kitchen doors, storage doors, and sliding doors, there is a case where a warp is gradually generated due to humidity and temperature. Therefore, in order to prevent warpage, a sheet of the same material is used on the front and back of a general door fitting to prevent it from warping on one side, or paper / waterproof resin / paper with a waterproof / moisture-proof sheet attached. Alternatively, a base plate made of paper / water-proof resin / paper / plate base material (actual flat plate 3-1186)
No. 34) is known. However, in order to improve the adhesiveness to the plate base material, the cost is increased by providing two paper layers.
