PROBLEM TO BE SOLVED: To provide a tool holder for effectively restraining chattering vibration of a cutting tool by using a member of a construction material superior in chattering resistance. SOLUTION: This tool holder has a tapered shank part 1 on the rear end, and has a tool holding part 3 connected to a flange part 2 arranged on the expanding diameter end, and is characterized by improving the chattering resistanceαexpressed by the product of rigidity K and the attenuationζratio by constituting a tool installing side prescribed length part of the tool holding part 3 out of a material having higher damping capability than the tapered shank part 1.
