PURPOSE:To obtain a heating/cooling roll free from an occurrence of temperature ununiformity in the width direction and flow direction of a heated/cooled material. CONSTITUTION:A rotatable outer cylinder 21 is provided concentrically to an inner cylinder 25 nonrotatably provided. A circular medium flow path 26 is formed between both the cylinders. The inner cylinder 25 is provided with a medium inlet port 40 and a medium outlet port 41 of slit shapes extending over approximately the full length thereof in the axial direction thereof. A medium supply path and a medium discharge path respectively connected to the medium inlet port 40 and the medium outlet port 41 are provided in the inner cylinder 25. Furthermore, a partition member 42 extending in the axial direction of the inner cylinder is provided between the medium inlet port and the medium outlet port so as to circumferentially interrupt the medium flow path 26. |
