PROBLEM TO BE SOLVED: To efficiently dry timber while compatibly suppressing internal cracking and shortening a drying time by acquiring data accurately reflecting the conditions of drying stress in the timber being dried. SOLUTION: The timber drying method comprises fixing a distortion detecting means 1 into the timber 2 and drying the timber 2 while controlling the drying conditions in accordance with data obtained from the distortion detecting means 1. The drying conditions are controlled in such a manner that, for example, when a distortion variation per one hour exceeds a preset value, there is a higher degree of potential for internal cracking and so the drying conditions are changed into a lower drying speed, and when the distortion variation is turned down to a preset value or less, there is a lower degree of potential for internal cracking and so the drying conditions are changed into a higher drying speed.
