PROBLEM TO BE SOLVED: To provide a treatment method for dimensionally stabilizing wood capable of efficiently and economically manufacturing a wood product having high dimensional stability by suppressing the dimensional change, cracking and warpage of wood at the time of drying and making it possible to short a drying period to a large extent by thermal drying not performing humidification control. SOLUTION: Wood is dried by successively performing a process (1) for preliminarily drying wood to bring the water content of the surface layer thereof to 25-60%, a process (2) for processing the wood into a predetermined shape, a process (3) for injecting a dimension stabilizer in the surface layer of wood and a process (4) for drying the wood under heating while degassing the same without substantially performing humidification from the outside to enhance not only a yield as dried wood but also the dimensional stability of wood.
