PROBLEM TO BE SOLVED: To provide a disc type tool of a laminated structure having a high damping characteristic and high rigidity and low in manufacturing cost. SOLUTION: The disc type tool 10 is a laminated structure constituted by partially connecting, laminating and fixing two to five pieces of discs, and a liquid material is permeated into small clearances between layers of a laminated body. It is desirable to arrange steel plates having quenching hardening capacity at least on both surface sides of the laminated body to improve rigidity of the disc type tool. Permeation of the liquid material to the small clearances between the layers of the laminated body uses positive pressure or negative pressure working on the liquid material or a capillary phenomenon. It is desirable that the liquid material is a resin material to be hardened in a state having viscoelasticity by leaving it naturally or by heat-treatment, etc.
