PROBLEM TO BE SOLVED: To provide a holder having high machining precision, a cutter main body, and a cutting tool to solve a problem of uneven machining precision in cutting off, although the holder is made thick and short and a material having high strength is adopted to increase mechanical strength and improve machining precision, in the cutting tool in which a cutting chip is attached to the holder. SOLUTION: This invention relates to the holder 2 for cutting tool in which a degree of face coarseness of a chip bearing surface 4 for fixing the cutting chip 3 is set in such a way that arithmetic average coarseness (Ra)=0.8μm or less, the cutter main body for cutting tool, and the cutting tool 1 constituted by attaching the cutting chip to the holder 2 for cutting tool or the cutter main body for cutting tool.
