摘要

A polishing device for polishing the flat surface part of a polished material W by a polishing tape T, comprising a polishing device body having a tubular rotary drum 3 having a precisely finished outer peripheral surface, a tape reel 41, a wind-up reel 42 for winding up the polishing tape T, and the polishing tape T, the rotary drum 3 further comprising an outer peripheral surface having an axial length longer than that of the polished material W crossing the surface thereof, wherein a slit 32 allowing the polishing tape T to be inserted after the polishing tape T on the tape reel 41 located in the rotary drum 3 is pulled out onto the outer peripheral surface of the rotary drum 3 and wound by one turn on the outer peripheral surface of the rotary drum 3 is provided in the rotary drum 3 in the axial direction, and a polishing stand 6 comprising a slide mechanism 7 for sliding the polishing stand 6 relative to the rotary drum 3 in the direction orthogonal to the axial direction of the rotary drum 3 to bring the flat surface part of the polished material W on the polishing stand 6 into contact with the polishing tape T wound on the rotary drum 3 when the polishing stand is slid.
