摘要

On one surface (surface 3) of the cushioning material 1, a peak 5 and a valley 7 are formed. The mountain part 5 and the valley part 7 are arrange|positioned periodically alternately longitudinally and horizontally. In addition, the ridge part 5 and the valley part 7 are not formed in the other surface (rear surface 5) of the cushioning material 1, but it is flat. The cushioning material 1 is equipped with resin foam 15a, 15b, and the adhesive layer 17 formed in the lamination|stacking surface of resin foam 15a, 15b. The adhesive layer 17 formed substantially parallel to the back surface 9 is exposed in the part of the predetermined height of the surface 3 of the corrugated uneven structure. By the adhesive layer 17, in planar view, many linear patterns 11 are formed.
