PROBLEM TO BE SOLVED: To provide a disk roll remarkably small in powder falling compared to a conventional one and having high thermal shock resistance. SOLUTION: The disk roll is used for carrying a member under a heated state, has a 1st disk roll part formed by laminating a plurality of 1st disks each comprising a material having a tendency to contract by heating and a 2nd disk roll part formed by laminating a plurality of 2nd disks each comprising a material having a tendency to expand by heating and the outer diameter of the 1st disk is larger than that of the 2nd disk.
