A pipe of a woodwind instrument (e.g., an upper joint of an oboe) having a through-hole running therethrough in its longitudinal direction is produced in such a way that a plastic lining layer composed of a thermoplastic material is formed on the interior wall of the pipe and the circumferential surfaces of tone holes of the pipe. The thermoplastic material is selected from generally-known plastic materials such as polyethylene, polypropylene, polystyrene, ABS resin, and POM resin. This prevents the inside of the pipe from being excessively expanded due to a player's moist breath in playing the woodwind instrument; hence, it is possible to prevent cracks or flaws from occurring on the pipe. In addition, this structure is superior in manufacturability and suited to mass production.
