Zusammenfassung:	PURPOSE:To manufacture dry timber which has high dimensional accuracy and no deformation due to internal stress. CONSTITUTION:The method for manufacturing a dry timber comprises the steps of (S1) introducing the timber into a dryer, (S2) first pressurizing it to a pressure of atmospheric pressure to 10kg/cm , raising it to a temperature of the normal temperature to 200 deg.C to dry it, then (S3) reducing the pressure without lowering the temperature, (S4) then removing and during it and (S5) returning it to the normal temperature and atmospheric pressure, and then taking it out.
