PROBLEM TO BE SOLVED: To provide a roll for transportation of a metallic material which is hard to occur a crack damage.SOLUTION: A roll 1 for transportation of a metallic material comprises a columnar shaft core 2, and an external cylinder 3 covering a peripheral surface of the shaft core 2. The external cylinder 3 is divided in an axial direction of the roll. Between the divided parts of the external cylinder 3, a clearance 31 for exposing a part of the peripheral surface of the shaft core 2 in a circumferential direction of the roll is formed. A groove 2a is formed in the exposed peripheral surface of the shaft core 2. At both ends of the groove 2a, a curve surface, which connects the groove 2a to the peripheral surface of the shaft core 2, is formed.
