In this case, for example, even if the plate-like member 32 has a thickness equivalent to the distance d2, when the packaging material 10 is attached to the plate-like member 32 as the packing body 12, the corner portion 32a of the plate-like member 32 is obtained. Can be protected by the first auxiliary portion 18 and the second auxiliary portion 20.

  In the packaging material 10 according to the present embodiment, the wave crest 14d of the core 14a extends in the first direction X. In this case, even if a load is applied from the plate-like member 32 to the buffer part 34 in the first direction X, deformation of the buffer part 34 can be sufficiently prevented. That is, the strength of the buffer portion 34 can be sufficiently ensured in the first direction X.

  In the packaging material 10 according to the present embodiment, the distance d7 between the fifth ruled line 22e and the seventh ruled line 22g and the distance d8 between the sixth ruled line 22f and the eighth ruled line 22h are the distance between the first ruled line 22a and the second ruled line 22b. It is larger than the distance d2. In this case, for example, even when the plate-like member 32 has a thickness equivalent to the distance d2, when the packing material 10 is attached to the plate-like member 32 as the packing body 12, the first auxiliary portion 18 and the second auxiliary portion The part 20 can be bent easily.

  The packaging material 10 according to the present embodiment has an opening 28 and a recess 30. Thereby, when the packing material 10 is attached to the plate-like member 32 as the packing body 12, the opening 28 and the recessed portion 30 can be used as a place for placing a fastening tool (screw or the like).
