A tool holder is provided which enables the coupling of a tool holder body, regardless of the size of its outside diameter, to a tapered shank, which is hardly influenced by centrifugal force generated at the time of high-speed rotation, and which can cause elastic deformation of the tapered shank effectively. The tool holder comprises the tapered hollow shank mounted on a machine tool spindle and the tool holder body coupled to the tapered shank. The tapered shank and the tool holder body are coupled to each other in the state where a part of the tapered shank is inserted in the tool holder body.
