PROBLEM TO BE SOLVED: To provide a bristle material for a polishing brush, and the polishing brush which can prevent contamination caused by the deposition of brush chips or grinding sludge by suppressing static electricity generated during polishing work, and is excellent in durability and can exhibit sustainable polishing performance. SOLUTION: The bristle material for the polishing brush is constituted by forming a conductive resin layer 2 containing carbon black particles of 5-40 wt.% on at least a part of a mono filament 1 composed of an abrasive material-containing thermoplastic resin composition in the surface longitudinal direction, and has a weight ratio of the mono filament 1 to the conductive resin layer 2 of 70-95:30-5.
