The thick paper () has a basis weight of 100 to 300 g/m, a thickness of 150 to 500 μm, and a density of 0.5 g/cmor greater. The diameter of the cylinder is 5 mm to 8 mm. A plurality of grooves () that are parallel to an axis (CL) of the cylinder are disposed in the outer circumferential surface or the inner circumferential surface of the cylinder.
