However, at this time, as shown in FIG. 24, a gap is secured between the second sheet 27 of the support 21 and the cone-shaped projection sheet 23, and further, the first sheet 25 of the support 21 A gap is secured between the step surface 35.

Thereafter, the conical projection sheet 23 is sealed between the seal sheet 9 and the storage sheet 7 by vacuum packaging. As a result, as shown in FIG. 21, the conical-projection-sheet packaging 1 is obtained.
Note that the cushion member 111 needs to have sufficient rigidity to reliably protect the plurality of conical protrusions 23b of the conical protrusion sheet 23 during vacuum packaging.

(5) Summary of Embodiment (5-1) Structure of Conical Projection Sheet Packing Body Conical projection sheet packaging 1 (an example of a conical projection sheet packaging) is a conical projection sheet. 23 (an example of a cone-shaped projection sheet), a storage sheet 7 (an example of a storage sheet), and a seal sheet 9 (an example of a seal sheet). The cone-shaped projection sheet 23 includes a base body 23a (an example of a base body) and a plurality of cone-shaped projections 23b (an example of a cone-shaped protrusion) formed on the surface of the base body 23a. The storage sheet 7 has a concave storage portion 31a (an example of a concave storage portion) in which the conical projection sheet 23 is stored. The seal sheet 9 is vacuum-packed with the conical projection sheet 23 between the seal sheet 9 and the storage sheet 7.
In this case, by using vacuum packaging, there is no gap between the storage sheet 7 and the seal sheet 9, and as a result, the conical projection sheet 23 is immovable between the storage sheet 7 and the seal sheet 9. . Therefore, the plurality of cone-shaped projections 23b of the cone-shaped projection sheet 23 are not easily damaged.
