To provide a tuning pin busing of a piano capable of suppressing dimensional changes caused by the influence of drying and wetting, accordingly preventing the generation of a gap between a tuning pin and a frame and stably holding the tuning pin, and to provide a method of manufacturing the tuning pin bushing of the piano.

A tuning pin bushing 6 is embedded in a pin hole 4 imparted in a frame 1 to support a tuning pin 5. The tuning pin bushing 6 is made to pass through the pin hole 4 is comprised of a bamboo material. Also, the tuning pin bushing 6 is formed of a cylindrical shape to allow the penetration of the tuning pin 5 through a pin insertion hole 7, and fibers of the bamboo material extend in an axial line direction of the tuning pin bushing 6.
