To provide a grinding rope allowing the judgment of replacement time by identifying the wear state of an edge body without interrupting a working operation.
A spiral edge body 30 having an edge body unit 20 with abrasive grains W for cutting fixed thereto on the side facing toward the outside is installed on a metallic rope 10 by winding, a rope covering member 40 of double layer structure formed of an inner layer 2 formed on the rope 10 side and an outer layer 42 formed on the outside of the inner layer 41 is formed in a spiral clearance in the blade body 30. The colors of the inner layer 41 and the outer layer 42 are differentiated from each other, and the inner layer 41 is formed radially with a specified thickness (d) in the area ranging from the outer peripheral surface 10a of the rope 10 to the position H of the edge body unit 20 where the abrasive grains W are fixed.
