Abstract: An optical structure includes an embossed layer having an embossed surface having a flat surface and an uneven surface, and an optical interaction layer covering and following the embossed surface. The optical interaction layer exhibits an optical function of the embossed surface. The uneven surface includes a first region, a second region, and a boundary region located between the first region and the second region. The regions each include a recess recessed from the flat surface. The recess in the first region is recessed from the flat surface to a first recess depth, the recess in the second region is recessed from the flat surface to a second recess depth, and the first recess depth is larger than the second recess depth. The recess in the boundary region is recessed from the flat surface to a third recess depth, and the third recess depth is larger than the first recess depth and larger than the second recess depth. The second region includes a plurality of linear regions regularly arranged on the embossed surface.

Abstract: In a sheet (12) of a roll body (10) wound on a core (11) along the circumferential direction of the core (11), each of first regions (12A) and each of second regions (12B) have a belt-like shape extending along a first direction and include an edge along the first direction. The edges extend along a direction crossing both an extending direction (D1) and a width direction (D2), and the first regions (12A) and the second regions (12B) are alternately arranged adjacent to each other. Accordingly, portions of the core (11) on which the first regions (12A) are wound and portions of the core (11) on which the second regions (12B) are wound change, thereby suppressing wrinkles in the sheet (12) wound on the core (11).
