率となるように水分調整されている。2. Description of the Related Art Conventionally, wood used for processing materials significantly reduces processing accuracy due to shrinkage or deformation of the wood during drying caused by a high internal water content. The water content is adjusted by artificial drying so as to have a predetermined water content.

割れや狂いの発生がある。[0005] In these drying methods, decompression or heating is applied to almost the entire surface of the wood, or high-frequency irradiation is performed. Of these methods, when the decompression is performed, the equipment cost of the apparatus is high. Since observation of the dry state cannot be performed, cracks and irregularities in the wood may occur.
