PROBLEM TO BE SOLVED: To provide a roller for thermocompression bonding in which the structure is easy and it is easy to carry out assembly and maintenance, there is strength which can perform thermocompression bonding certainly even if there is some irregularity, moreover there is the large homogeneity of temperature distribution making uniform bonding possible in a large area, and to provide a fixing method of an inner tube member of a hollow roller having a dual structure in a heating roller. SOLUTION: The heating roller comprises a hollow roller 1 and a stationary type heating element 7 in the hollow of the hollow roller, wherein since an inner tube member 2 of the hollow roller is fixed by a pin 10 inserted from an outer tube member 3 of the hollow roller, the structure is simple, the assembly is easily carried out and the inner tube member does not shift while used. In addition, since the inner tube member of the hollow roller is fixed at the center and by one pin, the misalignment by the expansion and contraction of the length direction of the inner tube member and the outer tube member can be suppressed in the minimum extent.
