The foam 115 and the lower crosslinked foam 125 are formed at positions corresponding to each other. Then, when the upper crosslinked foam member 110 and the lower crosslinked foam member 120 are bonded to each other, the upper crosslinked foam member 110 and the lower side are formed by the upper air layer forming groove and the lower air layer forming groove. The air layer 101 sealed to the outside is formed between the crosslinked foam members 120. The air layer 101 is formed in a generally spherical shape or the like, and the air layers 101 form spaces that are independent of each other, and accommodates air therein.

In the present embodiment, the upper air layer forming groove and the lower air layer forming groove may have a trapezoidal cross-sectional shape, and thus the air layer 101 may have a hexagonal cross-sectional shape.
