Title: ROLL BODY
Abstract:
In a sheet (12) of a roll body (10) rolled around a winding core (11) along the peripheral direction thereof, each first region (12A) and each second region (12B) have belt shapes extending along a first direction, and include edges along the first direction. The edges extend in directions intersecting with both the extending direction (D1) and the width direction (D2), and the first regions (12A) and the second regions (12B) are alternately arranged side by side. Thus, generation of wrinkles in the sheet (12) rolled around the winding core (11) is suppressed through changing of a portion at which the first region (12A) is rolled and a portion at which the second region (12B) is rolled.
