Abstract:
Provided is a roll body with which it is possible to effectively suppress the occurrence of a telescope phenomenon even if the ambient temperature during transportation and storage of the roll body becomes higher than when the roll body is manufactured. This roll body RB, which is configured by a strip-shaped web 2 being wound around a winding core 1 that thermally expands or contracts depending on the influence of the surrounding environment, is characterized in that the coefficient of linear expansion in the thickness direction of the web is in the range of 60 to 150 times the coefficient of linear expansion in the longitudinal direction, and the winding core has a linear expansion coefficient in the range of 20×10-6/K to 100×10-6/K and a Young's modulus in the range of 0.2 GPa to 0.5 GPa.
