Abstract
A wood member for a musical instrument, which is capable of preventing occurrence of damage, such as cracking, to thereby ensure smooth and stable operation of the musical instrument and maintain excellent appearance of the same over a long time period. The wood member has compressive internal stress remaining at least in an outer peripheral portion thereof by being subjected to heating processing, cooling processing, and moisture conditioning processing, in advance. A wood workpiece as a workpiece for the wood member is heated at a predetermined temperature, and the heated wood workpiece is cooled. The cooled wood workpiece is subjected to moisture conditioning such that compressive internal stress is generated at least in an outer peripheral portion of the wood workpiece.
