PROBLEM TO BE SOLVED: To provide a back boundary processed wood and a method for preparing it wherein looking such as appearance of a wood when it is completed is prevented from becoming worse caused by a back boundary channel formed on the wood and it can be easily applied to a framework construction method using a fitment and it can be given that cracking caused by back boundary processing is prevented from occurring. SOLUTION: After a back boundary channel 2 is formed on a wood main body 1 being a lumbering green wood, this is artificially dried. The back boundary channel 2 is a little deformed by this artificial drying in such a way that it is a little opened to the outside. In addition, as adjustment for back boundary, it is regularly cut into a wedge-shaped (a tapered or a V-shaped crosssection) regular channel 3. A wood plug 8 with the same wedge crosssection as that of this regular channel 3 is press-fitted into this regular channel 3 through an adhesive 9 and is integrated by embedding. In addition, it is finished by cutting finally the outer face into a required crosssectional shape to obtain a back boundary processed wood 10.
