A polishing device () includes a polishing brush () and a polishing brush holder () that holds the polishing brush (). The polishing brush holder () includes a shank (), a support mechanism () that has a sleeve () and supports the polishing brush () so as to be movable in an axial direction L of the shank (), and a moving mechanism () that moves the polishing brush () in the axial direction L. The polishing brush holder () includes a pressure sensor () that detects a load (sensor detection pressure (P)) applied from a workpiece (W) to the polishing brush () when the workpiece (W) is polished by the polishing brush () supported by the support mechanism (), and a control unit () that drives the moving mechanism () on the basis of the output (sensor detection pressure (P)) from the pressure sensor () to move the polishing brush () in the axial direction L.
