Zusammenfassung:	PURPOSE:To carry out winding what sort of synthetic resin sheet without causing a step trace by providing a step in approx. the same size as the thickness of the sheet to be wound, and forming the other areas on the outside circumferential surface than the step in a smooth arc of circle substantially. CONSTITUTION:At the outside circumferential surface a core 1 is provided with a step 2 approx. in the same side as the thickness of a synthetic resin sheet to be wound. The other areas of this surface than the step 2 are formed in a gradual arc of circle substantially, and thus the desired core material 1 is obtained.
