1. A wound body formed by winding a long sheet, wherein
the wound body is supportable by a support shaft,
the support shaft comprises a cylindrical outer peripheral part having a proximal end and a distal end, and is configured to be rotatable around a central axis of the outer peripheral part,
the outer peripheral part comprises a 1st projection located at the proximal end and projecting outward in a radial direction, and a 2nd projection located at the distal end and projecting outward in the radial direction, in which a projecting amount of the 2nd projection projecting outward in the radial direction with respect to the outer peripheral part is smaller than that of the 1 st projection,
the wound body comprises a core body having a cylindrical shape, and the long sheet wound around an outer periphery of the core body,
the core body comprises a cylindrical inner peripheral part having one end and an other end,
the inner peripheral part comprises a 1st recess part located at the one end and recessing outward in the radial direction, and a 2nd recess part located to extend from the one end to the other end and recessing outward in the radial direction, in which a recessing amount of the 2nd recess part recessing outward in the radial direction with respect to the inner peripheral part is smaller than that of the 1st recess part,
the core body is mountable on the outer periphery of the support shaft from the one end side of the core body, and from the distal end side of the support shaft,
the support shaft and the core body are integrally rotatable around the central axis by engagement of the 1st projection with the 1st recess part in a state where the core body is mounted on the outer periphery of the support shaft, and
the circumferential position of the 1st projection around the central axis is aligned with the circumferential position of the 1st recess part around the central axis by engagement of the 2nd projection with the 2nd recess part when the core body is mounted on the outer periphery of the support shaft.
