PROBLEM TO BE SOLVED: To provide a twisted brush capable of preventing buckling, bending and deviation of the root part of a brush part when applying a pressure and an impact thereto from the outside even under inferior working conditions when executing various work such as deburring, grinding, polishing, surface treating and cleaning a cleaning object face, capable of forming the product precision with extremely reduced core deviation and high straightness, preventing falling of a brush piece, reducing the weight, and being usable as a rotating body with the extremely reduced core deviation. SOLUTION: This twisted brush for executing various types of work has a retaining part, a support part, a brush part and a core material, the retaining part and the support part are formed of a wire material, the brush part is formed by clamping a plurality of brush pieces by at least the wire rod in the outer circumference part of the retaining part, and the core material is formed to penetrate the support part and the retaining part.
