PROBLEM TO BE SOLVED: To provide a polishing jig completely and easily attaches/detaches an elastic polishing body to/from a support portion. SOLUTION: This jig includes: the elastic polishing body 3 in which a flange portion 32 is provided at a peripheral edge portion of a dome portion 31; the support portion 2 which supports the flange portion 32 of the elastic polishing body 3; a roughly ring-shaped pressure member 4 which presses the flange portion 32 to the support portion 2; and an attachment/detachment portion 5 which attaches/detaches the pressure member 4 and the flange portion 32 to/from the support portion 2. The attachment/detachment portion 5 includes: a shaft portion 53 which is inserted in notches 222, 41 respectively formed at the support portion 2 and the pressure member 4 and of which one edge is rotatably attached at the support portion 2; a first washer 551 which is provided at the shaft portion 53 and fitted with the support portion 2; and an eccentric cam 54 which is rotatably provided on the other edge side of the shaft portion 53. The eccentric cam 54 supports and secures the support portion 2, the pressure member 4, and the flange portion 32 by sandwiching them in a space with the first washer 551 when it rotates in one direction, and securing of the support portion 2, the press member 4 and the flange portion 32 is released when it rotates in the other direction.
